By Order of the Board of Directors,

Michael Weinstock

Chairman

Los Angeles, California

GRILL CONCEPTS, INC.

Our board of directors is soliciting your proxy for the annual meeting of stockholders to be held at the Daily Grill in Santa Monica at 2501 Colorado Avenue – B-190, Santa Monica, CA 90404, on Wednesday, June 20, 2007 at 10:00 a.m. and at any and all adjourned sessions of the annual meeting.

We are mailing our annual report for the fiscal year ended December 31, 2006, to our stockholders with this notice and proxy statement (including the form of proxy) on or about May 4, 2007.

Only stockholders of record at the close of business on April 20, 2007 will be entitled to vote at the annual meeting. The majority of the shares of common stock issued and outstanding and entitled to vote on the record date must be present in person or by proxy to have a quorum for the transaction of business at the annual meeting. Shares of common stock present in person or represented by proxy (including shares which abstain, withhold the vote or do not vote with respect to one or more of the matters presented for stockholder approval) will be counted for purposes of determining whether a quorum exists for a matter presented at the annual meeting. At the close of business on April 20, 2007, we had 6,422,916 shares of common stock issued and outstanding.

Your vote is very important. If you do not vote your shares, you will not have an impact with respect to the issues to be voted on at this annual meeting. In addition, banks and brokers cannot vote on their clients’ behalf on “non-routine” proposals.

The holders of all outstanding shares of Common Stock are entitled to one vote for each share of Common Stock registered in their names on the books of the Company at the close of business on the record date. Additionally, every stockholder voting for the election of directors may cumulate such stockholder’s votes and give one candidate a number of votes equal to the number of directors to be elected multiplied by the number of shares held by the stockholder as of the record date, or distribute such stockholder’s votes on the same principle among as many candidates as the stockholder may select, provided that votes cannot be cast for more than the number of directors to be elected. However, no stockholder shall be entitled to cumulate votes unless the candidate’s name has been placed in nomination prior to the voting and the stockholder, or any other stockholder, has given notice at the meeting prior to the voting of the intention to cumulate the stockholder’s votes.

In order to be elected as directors, each of the nominees for director must receive a plurality of the votes cast at the annual meeting. Ratification of the selection of Moss Adams LLP as our independent registered public accounting firm for the 2007 fiscal year will require the affirmative vote of a majority of the shares of common stock present or represented by proxy at the annual meeting.

Shares that abstain from voting on a particular proposal, and shares held in “street name” by brokers or nominees who indicate on their proxies that they do not have discretionary authority to vote such shares on a particular proposal, will not be counted as votes “in favor” of such proposal, and will also not be counted as votes cast or shares voting on that proposal. Accordingly, abstentions and “broker non-votes” will have no effect on the

1

voting on a proposal that requires the affirmative vote of a certain percentage of the votes cast or shares voting on a proposal. However, abstentions are considered to be present or represented in determining whether a quorum exists on a given matter.

If you complete and submit your proxy, the persons named as proxies will vote the shares represented by your proxy in accordance with your instructions. If you submit a proxy card but do not fill out the voting instructions on the proxy card, the persons named as proxies will vote the shares represented by your proxy as follows:

To ensure that your vote is recorded promptly, please vote as soon as possible. To vote by proxy, please complete, sign and mail the proxy card in the enclosed postage-paid envelope.

Stockholders that attend the annual meeting and wish to vote in person will be given a ballot at the meeting. If your shares are held in “street name” and you want to attend the annual meeting, you must bring an account statement or letter from the brokerage firm or bank holding your shares showing that you were the beneficial owner of the shares on the record date. If you want to vote shares that are held in “street name” or are otherwise not registered in your name, you will need to obtain a “legal proxy” from the holder of record and present it at the annual meeting.

You may revoke or change your proxy at any time before it is voted. For a stockholder “of record”, meaning one whose shares are registered in his or her own name, to revoke or change a proxy, the stockholder may follow one of the procedures listed below.

If you are a beneficial owner of our common stock, and not the stockholder of record (for example your common stock is registered in “street name” with a brokerage firm), you must follow the procedures required by the holder of record, which is usually a brokerage firm or bank, to revoke or change a proxy. You should contact the stockholder of record directly for more information on these procedures.

We will bear the expense of soliciting proxies. Our officers and certain other employees, without additional remuneration, may solicit proxies personally or by telephone, e-mail or other means.

Our Annual Report on Form 10-K for the year ended December 31, 2006, which is not part of the proxy soliciting materials, is included with this Proxy Statement.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The table below shows the number of our shares of common stock beneficially owned as of April 20, 2007 by:

The number of shares beneficially owned by each 5% holder, director or executive officer is determined by the rules of the SEC, and the information does not necessarily indicate beneficial ownership for any other purpose. Under such rules, beneficial ownership includes any shares over which the person or entity has sole or shared voting power or investment power and also any shares that the person or entity can acquire within 60 days of April 20, 2007 through the exercise of any stock option or other right. For purposes of computing the percentage of outstanding shares of common stock held by each person or entity, any shares that the person or entity has the right to acquire within 60 days after April 20, 2007 are deemed to be outstanding with respect to such person or entity but are not deemed to be outstanding for the purpose of computing the percentage of ownership of any other person or entity. Unless otherwise indicated, each person or entity has sole investment and voting power (or shares such power with his or her spouse) over the shares set forth in the following table. The inclusion in the table below of any shares deemed beneficially owned does not constitute an admission of beneficial ownership of those shares. As of April 20, 2007, there were 6,422,916 shares of common stock issued and outstanding.

PROPOSAL I

The first proposal to be voted on is the election of seven directors. The Board’s nominees are Robert Spivak, Michael Weinstock, Philip Gay, Glenn Golenberg, Stephen Ross, Robert Fell and Bruce Schwartz. Each of the nominees, except Mr. Fell, is currently serving as a director of the company. If elected, each of the nominees will serve a one-year term and will be subject to reelection next year along with the other directors.

Biographical information about each of the nominees is included below. There are no family relationships among any of our directors, nominees for director and executive officers.

The Board of Directors has no reason to believe that any nominee will be unable to serve or decline to serve as a director if elected. If a nominee becomes unable or unwilling to accept nomination or election, the Board will either select a substitute nominee or will reduce the size of the Board. If you have submitted a proxy and a substitute nominee is selected, your shares will be voted for the election of the substitute nominee.

In accordance with the company’s bylaws, directors are elected by a plurality vote of shares represented and entitled to vote at the meeting. That means the seven nominees will be elected if they receive more affirmative

5

votes than any other nominees. In accordance with applicable law, in electing directors, stockholders may cumulate their votes and give one candidate a number of votes equal to the number of directors to be elected multiplied by the number of shares held by the stockholder as of the record date, or distribute such stockholder’s votes on the same principle among as many candidates as the stockholder may select, provided that votes cannot be cast for more than the number of directors to be elected. However, no stockholder shall be entitled to cumulate votes unless the candidate’s name has been placed in nomination prior to the voting and the stockholder, or any other stockholder, has given notice at the meeting prior to the voting of the intention to cumulate the stockholder’s votes.

6

In considering your vote with respect to the election of directors pursuant to Proposal I, you should consider the discussions of “Executive Compensation” and “Corporate Governance” and the other discussions contained in this Proxy Statement.

PROPOSAL II

Our board, on the recommendation of the audit committee, has selected the firm of Moss Adams LLP as our registered public accounting firm for fiscal 2007. Moss Adams LLP has served as our registered public accounting firm since 2004. Although stockholder approval of the board’s selection of Moss Adams LLP is not required by law, the board believes that it is advisable to give stockholders an opportunity to ratify this selection. If this proposal is not approved at the annual meeting, the board will reconsider its selection of Moss Adams LLP.

Representatives of Moss Adams LLP are expected to be present at the annual meeting. They will have the opportunity to make a statement if they desire to do so and will be available to respond to appropriate questions from stockholders.

In considering your vote with respect to the ratification of our selection of Moss Adams LLP as our registered public accounting firm pursuant to Proposal II, you should consider the discussion of “Relationship with Independent Registered Public Accounting Firm” and the other discussions contained in this Proxy Statement.

EXECUTIVE COMPENSATION

Our compensation program is designed to attract and retain key employees, motivating them to achieve and rewarding them for superior performance. Additionally, the stock option component of our compensation program is designed to promote an ownership mentality among management, key employees and our Board of Directors. Finally, we seek to ensure that our compensation program is fundamentally fair for all stakeholders in the company, including stockholders, management and non-management employees.

In general, our compensation program is designed to reward overall company performance with recognition of individual contributions to that performance. Except with respect to executive officers serving under employment agreements, our compensation committee conducts an annual review of all elements of each executive officer’s compensation and adjusts each element of compensation, in particular base salary and stock option grants, to reflect experience, expertise and responsibilities of each executive officer.

All of our executive officers participate in a cash bonus program pursuant to which a bonus pool is established based on financial performance of the company relative to budgeted profitability targets and other performance criteria established by the compensation committee annually. The bonus pool is split among the executive team based on a combination of predetermined maximum bonuses for each officer stated as a percentage of base salary and compensation committee discretion to allocate portions of the bonus pool to reflect individual contributions to overall company performance.

Stock price performance has not been a factor in determining annual compensation because the price of the company’s common stock is subject to a variety of factors outside of management’s control. Stock price performance is, however, reflected in compensation through selected annual grants of stock options to executive officers.

Elements of compensation for our executives presently include salary, participation in our executive bonus pool and periodic stock option grants as well as participation in broad based benefit plans available to all employees, including health, disability and life insurance.

It is the compensation committee’s intention to set base salaries of our executive officers sufficiently high so as to attract and retain a strong motivated leadership team but not so high as to create excessive wealth to the detriment of the company or other stakeholders. The compensation committee reviews executive officer salaries annually at its regularly scheduled annual meeting, typically held in June of each year. At this meeting, our compensation committee will make adjustments to base salary, as it deems appropriate, for the upcoming fiscal year to reflect the evolving nature, scope and size of our enterprise. In reviewing and adjusting base salary, the compensation committee may review compensation data for comparable companies to establish ranges of compensation suitable to retain the company’s executive officers but does not benchmark salaries to place executive officers within a specific segment of compensation among its competitors.

In conjunction with the hiring of the company’s CEO and CFO, the compensation committee fixed the base salaries of both the CEO and CFO in accordance with the practices described above and in accordance with the terms of a written offer of employment to our CFO and a formal negotiated employment agreement with our CEO.

8

At the annual meeting, the compensation committee will also review and approve and adopt, as appropriate, management incentive plans for the coming year and grant stock options selectively to executive officers and other eligible employees.

It has been the compensation committee’s intent to use participation in the company’s executive bonus plan as the principal means of rewarding superior company financial performance and to use periodic grants of stock options as the principal means of creating wealth accumulation opportunities and an equity ownership mentality for company executives. As among the executive officers, the compensation committee takes into account the anticipated contributions to the company’s success and corresponding responsibilities of each executive officer in fixing the maximum percentage bonus each executive officer is eligible to receive under the executive bonus plan. With regard to grants of stock options, the compensation committee takes into account the then current stock and option holdings of each executive officer in determining appropriate levels of options to be granted to create both wealth accumulation opportunities and ownership mentality. In particular, new hires to senior positions are believed to merit larger stock option grants to provide strong incentives for their efforts to grow the company. On the other hand, certain long-time officers of the company, such as the company’s Chairman and Executive Vice President, are already major stockholders of the company and, as such, the compensation committee may elect to decrease or eliminate stock option grants. All employees of the company are eligible to participate in the company’s stock option plan and the compensation committee has historically made stock option grants to all, or substantially all, employees having management responsibilities on hiring and periodically thereafter as the committee deems appropriate to create continual incentives through equity based wealth accumulation opportunities.

We choose to pay each element of compensation, including compensation under our executive bonus plan, in order to attract and retain the necessary executive talent, reward annual performance and provide incentive for their balanced focus on long-term strategic goals as well as short-term performance. The amount of each element of compensation is determined by or under the direction of our compensation committee. The compensation committee receives recommendations from the company’s CEO regarding compensation of various executives but the CEO does not participate in any deliberations of the compensation committee and the committee may choose to follow or ignore the recommendations of the CEO. The compensation committee uses the following factors to determine the amount of salary and other benefits to pay each executive:

These elements fit into our overall compensation objectives by helping to secure the future potential of our operations, facilitating our development of new restaurant properties, providing proper compliance and regulatory guidance, and helping to create a cohesive team.

Our policy for allocating between long-term and currently paid compensation is to ensure adequate base compensation to attract and retain personnel, while providing incentives to maximize long-term value for our company and our stockholders. Likewise, we provide cash compensation in the form of base salary to meet competitive salary norms. We provide participation in the executive bonus plan to reward superior short-term financial performance and individual contributions to that performance. We also provide non-cash stock based compensation in the form of stock option grants to reward the creation of long-term value.

9

While, historically, we have not specifically sought to establish specific ranges of allocations as among cash and non-cash and fixed and variable compensation, the compensation committee will consider the relative allocations generally with an emphasis being placed on non-cash and variable compensation being a substantial element of overall compensation. In establishing such targeted allocations, and in establishing levels and terms of option grants, the compensation committee takes into account existing stock holdings, historic stock option grants and accumulated gains on stock option grants. Where holdings, past grants and accumulated gains are deemed to create sufficient levels of equity incentive and wealth growth potential, the compensation committee will consider reducing or foregoing future stock option grants to subject executives. Moreover, in establishing the amounts, types and allocation among types of compensation of executive officers, the compensation committee will take into account the various stakeholders of the company, including stockholders and non-executive employees, with a view to creating an environment of mutual interests among all stakeholders.

With respect to the timing of stock option grants, the compensation committee typically only makes such grants on the initial hiring of employees and in conjunction with the compensation committee’s annual review of compensation. The compensation committee has adopted as a policy a specific prohibition of timing stock option grants, and has made no stock option grants, to coordinate with the release of material non-public information in any manner designed to affect the value of executive compensation.

In addition to salary, participation in the executive bonus plan and periodic stock option grants, the company provides certain benefits designed to attract and retain executive officers and other employees, including life, health and disability insurance and participation in a 401K plan. Except as otherwise provided for in employment agreements, such benefits are broadly available to all employees on substantially identical terms. The company may make matching contributions to the 401K plan.

Section 162(m) of the Internal Revenue Code of 1986, as amended, or the code, generally disallows a tax deduction to public companies for compensation in excess of $1 million paid to the corporation’s chief executive officer and four other most highly paid executive officers. Qualifying performance-based compensation will not be subject to the deduction limitation if certain requirements are met. Our compensation committee will periodically review the potential consequences of Section 162(m) and may structure future performance-based executive compensation to comply with certain exemptions in Section 162(m). However, we reserve the right to use our judgment to authorize compensation payments that do not comply with the exemptions in Section 162(m) when we believe that such payments are appropriate and in the best interests of the stockholders, after taking into consideration changing business conditions or the officer’s performance.

We did not utilize the services of a compensation consultant during 2006. In conjunction with the transition of senior management away from founding shareholders, we have retained Vivient Consulting, a compensation consultant, to review existing compensation of management and to make recommendations to the compensation committee in order to attract, motivate and properly compensate senior management.

The compensation committee is responsible for discharging the responsibilities of the board with respect to the compensation of our executive officers. The compensation committee sets performance goals and objectives for the chief executive officer and the other executive officers, evaluates their performance with respect to those goals and sets their compensation based upon the evaluation of their performance. In evaluating executive officer pay, the compensation committee may retain the services of a compensation consultant and consider recommendations from the chief executive officer with respect to goals and compensation of the other executive officers. The compensation committee assesses the information it receives in accordance with its business judgment. The compensation committee also periodically reviews director compensation. All decisions with

10

respect to executive and director compensation are approved by the compensation committee and recommended to the full board for ratification.

The compensation committee is responsible for administering all of our equity-based plans. The committee may, however, authorize the chair of the compensation committee to grant individual stock awards upon the hiring of new employees between scheduled meetings of the compensation committee. The compensation committee also periodically reviews compensation and equity-based plans and makes its recommendations to the board with respect to these areas.

The compensation committee has reviewed and discussed the Compensation Discussion and Analysis (the “CD&A”) for the year ended December 31, 2006 with management. In reliance on the reviews and discussions referred to above, the compensation committee recommended to the board, and the board has approved, that the CD&A be included in the proxy statement for the year ended December 31, 2006 for filing with the SEC.

By the Compensation Committee of the Board of Directors:

Stephen Ross, Compensation Committee Chair

Glenn Golenberg, Compensation Committee Member

Bruce Schwartz, Compensation Committee Member

The following table includes information concerning compensation for the year ended December 31, 2006 for our CEO and our CFO, and the three most highly compensated executive officers (other than the CEO and CFO) during the year:

11

It is the compensation committee’s intention to set base salaries of our executive officers sufficiently high so as to attract and retain a strong motivated leadership team but not so high as to create excessive wealth to the detriment of the company or other stakeholders. During 2006, Robert Spivak retired as our CEO and we appointed Philip Gay, our then CFO, to fill the CEO position. In conjunction with his elevation to the CEO role, we entered into a new employment agreement with Mr. Gay increasing his base salary from $245,861 to $275,000. During 2006, following the promotion of Philip Gay, we hired Wayne Lipschitz as our CFO and fixed his initial salary at $200,000 annually. In setting base salaries for fiscal 2006, we reviewed salary compensation of officers with comparable qualifications, experience and responsibilities at comparable companies. We also considered the past and expected future contributions of our executive officers in achieving our goals. It is not our policy to benchmark the pay our CEO or CFO to their peers but rather to set compensation on a basis relative to the scope and nature of responsibilities involved, the financial resources available and the compensation of other members of our senior management team, taking into account ranges of pay to similarly situated executives at similar companies. We believe that this gives us the opportunity to attract and retain talented managerial employees both at the senior executive level and below.

Our compensation committee establishes an annual bonus incentive pool for our executives. At the beginning of fiscal year 2006, our compensation committee established the terms of the bonus pool. Under the terms of the 2006 plan, each executive was eligible to earn bonuses ranging from 25% to 50% of their base pay based on achieving budget at between 80% and 110% of our financial plan for the fiscal year. The compensation committee maintains the discretion to either pay or not pay, at its discretion after completion of the fiscal years, bonuses as it deems appropriate. During fiscal 2005, the company attained 100% of its target under its financial plan and the compensation committee elected to award cash bonuses in 2006 based on the bonus pool. As a result, the company paid cash bonuses totaling $307,688 to its executive officers, representing 32% of the aggregate base salary of the executives and ranges of 25% to 50% of base salary.

We intend that our stock option program is the primary vehicle for offering long-term incentives and rewarding our executive officers and key employees. We also regard our stock option program as a key retention tool. This is a very important factor in our determination of the terms of options granted, including the number of underlying shares that are granted in connection with that award. Because of the direct relationship between the value of an option and the market price of our common stock, we believe that granting stock options is the best method of motivating the executive officers to manage our company in a manner that is consistent with the interests of our company and our stockholders.

Option Awards Granted.    We grant options to our executive officers and key employees at the time of hiring and, thereafter, at the time of the compensation committee’s annual review of compensation based upon prior performance, the importance of retaining their services and the potential for their performance to help us attain our long-term goals. However, there is no set formula for the granting of options to individual executives

12

or employees. During 2006, we granted stock options to purchase 183,250 shares of common stock, or 2.9% of our outstanding stock on a fully diluted basis. Of the options granted during 2006, 94,000, or 51%, were to named executive officers and the balance was to other officers, non-employee directors and key employees. Of the options granted to named executive officers, 80,000, or 44%, were granted in conjunction with the promotion of Philip Gay from the CFO position to the CEO position and the hiring of Wayne Lipschitz as CFO.

Timing of Grants.    Stock option awards to our executive officers and other key employees have, historically, been limited to the commencement of employment and annually thereafter in conjunction with the review of the individual performance of our executive officers. This review takes place at the regularly scheduled quarterly meeting of the compensation committee, which is typically held in June of each year. Stock option awards are granted to our non-employee directors on the date of our annual meeting of stockholders. Grants to newly hired employees are effective on the employee’s first day of employment, and to facilitate this practice, the compensation committee may authorize the chair of the compensation committee to grant individual stock awards to non-executive employees between scheduled meetings of the compensation committee. The compensation committee has adopted as a policy a specific prohibition of timing stock option grants, and has made no stock option grants, to coordinate with the release of material non-public information in any manner designed to affect the value of executive compensation. The exercise price of all stock options is set at the prior day’s closing price of our common stock on Nasdaq.

Stock Ownership Guidelines.    We do not presently maintain any guidelines or requirements with respect to minimum number, or value, of our shares to be owned by our executive officers or directors. In determining whether to grant stock option awards, and the number of shares covered by stock option awards, we will, however, consider the number of shares held by an executive officer to determine whether additional grants will serve to motivate performance.

Each of our executive officers is provided with a dining card providing dining privileges at our company operated restaurants in the amount of $2,000 per quarter. Except for such dining privilege and as otherwise specifically provided for under employment agreements, all of our executives are entitled to the same benefits as are available to all of our employees. We generally provide to all of our employees, including our executive officers, group health, dental, life and long-term disability insurance, paid parking and participation in our 401(k) plan. In this regard it should be noted that we do not provide pension arrangements, post-retirement health coverage, or similar benefits for our executives or employees.

Pursuant to the terms of the employment agreement of Philip Gay, entered into during 2006 in conjunction with his promotion to the CEO position, we provide to Mr. Gay certain negotiated perquisites, in addition to participation in the executive bonus plan and participation in all other benefit plans available to senior executives, including the use of a company automobile plus payment of repair, maintenance and insurance costs with respect to such automobile in an amount not to exceed $10,000 annually and a term life insurance policy in the amount of $1,000,000.

Pursuant to his hiring as CFO, we agreed to provide to Wayne Lipschitz, in addition to other benefits generally available to all executive officers, reimbursement of premiums payable to maintain Mr. Lipschitz health insurance pursuant to COBRA until such time as Mr. Lipschitz was eligible under the company plan.

13

Grants of Plan-Based Awards

The following table sets forth certain information with respect to stock options granted during or for the fiscal year ended December 31, 2006 to each of our named executive officers:

The compensation committee granted stock options under the company’s stock option plans to Philip Gay on March 19, 2006, in connection with his promotion to CEO, and to Wayne Lipschitz on July 20, 2006, in connection with his hiring as CFO. Stock option grants to all other employees, including other executive officers, were made on June 21, 2006 in conjunction with the regular annual meeting of the compensation committee to approve option grants. In keeping with our standard policy and practice, the exercise price of the stock options that were awarded during 2006 was the prior day’s closing price of our common stock as reported on Nasdaq. The applicable option price was $3.19 in the case of Mr. Gay, $3.20 in the case of Mr. Lipschitz, and $3.16 for all other option grants. The terms of the options granted to Mr. Gay provide for vesting in three equal annual installments commencing one year from the date of grant. The terms of all other options granted to executive officers during 2006 provide for vesting in five equal annual installments commencing one year from the date of grant. All of the options granted to executive officers during 2006 have a life of 10 years.

Outstanding Equity Award at Fiscal Year-End

The following table includes certain information with respect to the number of all unexercised options previously awarded to the named executive officers at December 31, 2006.

15

The following table includes certain information with respect to options exercised by executive officers named above during the fiscal year ended December 31, 2006.

We do not provide pension arrangements or post-retirement health coverage for our executives or employees.

We do not provide any nonqualified defined contribution or other deferred compensation plans.

Other Post-Employment Payments

Robert Spivak Post-Retirement Consulting Agreement—In conjunction with, and pursuant to the terms of the Employment Agreement of Robert Spivak, we agreed to retain Mr. Spivak as a consultant for a period of ten years following his retirement. Under the terms of that Consulting Agreement, we agreed to pay to Mr. Spivak $12,500 per month and Mr. Spivak agreed to provide an estimated 40 hours per month of services. Additionally, we agreed to provide to Mr. Spivak use of an office, a $1,000 per month restaurant meal allowance and continued medical, life and disability insurance and, for a period of 18 months, an automobile.

Change in Control Agreements—In September 2005, we entered into Change in Control Agreements, on substantially identical terms, with each of Michael Weinstock, Philip Gay, John Sola and Louie Feinstein. Under the Change in Control Agreements, each of the covered employees is entitled to payment of a severance payment in the event that his employment is terminated in connection with a change in control. The severance benefits are payable if the employee is terminated within 90 days prior to or one year following a change in control, unless termination is for cause or voluntary resignation or death or disability.

Severance benefits consist of a lump sum cash payment equal to one and one-half times the sum of (1) the employee’s highest annual salary rate within 3 years prior to the date of termination, and (2) the annualized average bonuses and incentive pay during the 2 years prior to the date of termination. In the event of such termination, all unvested stock options held by each covered employee will immediately be fully vested and exercisable. Additionally, the employees will be entitled, for a period of two years, to group medical, dental, life and disability insurance subject to reduction or termination in the event the employee has concurrent coverage through another plan. In addition, if the employees are required to pay any excise tax as a result of the severance payment, we will pay an additional amount to the employees to compensate for any such excise tax.

16

Wayne Lipschitz Change of Control Agreement—Pursuant to the terms of a June 2006 offer letter setting out the terms of employment of Wayne Lipschitz as our CFO, we agreed to pay to Mr. Lipschitz severance pay in an amount equal to 3 months of base salary if we terminate Mr. Lipschitz other than for cause. The offer letter provides that, after one year of continuous employment, Mr. Lipschitz shall be entitled to severance pay in an amount equal to 6 months of base salary if his employment is terminated within one year of a change in control.

Other than as noted above, all of our employees are employees-at-will and as such do not have employment contracts with us and we have no agreements, written or oral, to provide any payments, including any post-retirement health coverage, to our executives or employees upon termination or a change-in-control.

The following tables provides information regarding estimated amounts that would have been paid, or payable, to each of the named executive officers had their employment terminated on December 31, 2006 under various circumstances, including a change of control. Information relating to Robert Spivak reflects amounts payable under Mr. Spivak’s consulting agreement that became effective upon his retirement during 2006.

DIRECTOR COMPENSATION

The following table provides compensation information for the year ended December 31, 2006 for each member of our Board of Directors:

18

We review the level of compensation of our non-employee directors on an annual basis. To determine how appropriate the current level of compensation for our non-employee directors is, we have historically obtained data from a number of different sources including:

We compensate non-employee members of the board through a mixture of cash and equity-based compensation. Beginning June 2006, each non-employee director receives an annual retainer of $4,000, payable in quarterly installments of $1,000, for his services as a director. Each member of the audit committee receives an annual retainer of $5,000, payable in quarterly installments of $1,250. Each member of the compensation committee receives an annual retainer of $3,000, payable in quarterly installments of $750. In addition, the chairman of the audit committee and compensation committee receives an annual retainer of $3,000 payable in quarterly installments of $750. We also reimburse expenses incurred by non-employee directors to attend board and committee meetings, and a food credit of $2,000 annually.

Prior to June 2006, non-employee directors received an annual retainer of $4,000, payable in quarterly installments of $1,000, an annual retainer for service on the audit committee of $4,000, payable in quarterly installments of $1,000, an annual retainer for service on the compensation committee of $2,000, payable in quarterly installments of $500, and a food credit of $2,000 annually and reimbursement of expenses.

On the date of the initial appointment or election of each non-employee director, the non-employee director receives a stock option grant to purchase 6,250 shares of our common stock at a price equal to the fair market value of our common stock on the date of grant. On the date of each annual meeting of stockholders following initial appointment or election, each non-employee director receives an annual stock option grant to purchase 5,000 shares of our common stock, plus 1,000 shares for each committee on which a non-employee director serves, at a price equal to the fair market value of our common stock on the date of grant.

Directors who are also our employees do not receive cash or equity compensation for service on the board in addition to compensation payable for their service as employees of Grill Concepts.

We do not presently maintain any guidelines regarding the minimum value of our stock that a non-employee director must own.

The following table provides information about securities authorized for issuance under our equity compensation plans as of December 31, 2006:

CORPORATE GOVERNANCE

The board consists of seven directors. During the fiscal year ended December 31, 2006, the board held a total of four meetings. Each director attended at least 75% of the total number of meetings of the board and at least 75% of the meetings of all committees on which he served. It is our policy that directors are expected to attend the annual meeting of stockholders. All the directors attended the 2006 annual meeting of stockholders.

The board has determined that each of the directors, with the exception of Messrs. Gay, Spivak and Weinstock, qualify as “independent” as defined by applicable Nasdaq and SEC rules. In making this determination, the board has concluded that none of these members has a relationship that, in the opinion of the board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Glenn Golenberg serves as lead director and presides over meetings of the independent directors.

The board currently has, and appoints members to, two standing committees: the audit committee and the compensation committee. Each member of these committees is independent as defined by applicable Nasdaq and SEC rules. Each of the committees has a written charter approved by the board. The current members of the committees are identified below:

20

The audit committee is composed of three independent directors, Messrs. Golenberg, Ross and Schwartz, each of whom meets the independence and financial literacy requirements as defined by applicable Nasdaq and SEC rules. The audit committee assists the board in its general oversight of our financial reporting, internal controls, legal compliance, ethics programs and audit functions, and is directly responsible for the appointment, evaluation, retention and compensation of the registered public accounting firm. The board has determined that Mr. Golenberg qualifies as an “audit committee financial expert” in accordance with the applicable rules and regulations of the SEC.

The audit committee acts under the terms of a written charter that was most recently amended in February 2004. A copy of the audit committee charter is attached to this Proxy Statement as Appendix A. The audit committee met four times during the fiscal year ended December 31, 2006. For more information regarding the audit committee, please refer to the “Report of Audit Committee” beginning on page 23.

The compensation committee, which is appointed by the board, is composed of three non-employee, independent directors as defined by applicable Nasdaq rules. The committee is responsible for establishing and administering the policies that govern both annual compensation and equity ownership. It reviews and approves salaries, bonus and incentive compensation, perquisites, equity compensation, and all other forms of compensation for our executive officers, including the chief executive officer. The compensation committee is also responsible for reviewing and administering our incentive compensation plans, equity incentive programs and other benefit plans. It periodically reviews and makes recommendations to the board with respect to director compensation.

The compensation committee acts under the terms of a written charter adopted in April 2007. A copy of the compensation committee charter is attached to this Proxy Statement as Appendix B. The compensation committee met two times during the fiscal year ended December 31, 2006. For more information regarding the compensation committee, please refer to the “Report of Compensation Committee” beginning on page 9.

The Board of Directors does not maintain a standing Nominating Committee. Instead, the Board has adopted, by Board resolution, a process of nominating directors wherein nominees must be selected, or recommended for the board’s selection, by a majority of the independent directors with independence determined in accordance with Nasdaq standards. Because of the relatively small size of the Board and the current demands on the independent directors, the Board determined that the nomination process would best be carried out, while maintaining the independence of the nominating process, by drawing upon the resources of all Board members with the requirement that nominees be selected by a majority of the independent directors.

In the event of a vacancy on the board, the process followed by the independent directors in nominating and evaluating director candidates includes requests to board members and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates and interviews of selected candidates by members of the board.

In considering whether to recommend any particular candidate for inclusion in the board’s slate of recommended director nominees, the independent directors apply criteria adopted by the board. These criteria include the candidate’s integrity, business acumen, knowledge of our business and industry, experience, diligence, absence of conflicts of interest and the ability to act in the interests of all stockholders. No specific weights are assigned to particular criteria and no particular criterion is a prerequisite for each prospective nominee. We believe that the backgrounds and qualifications of our directors, considered as a group, should

21

provide a composite mix of experience, knowledge and abilities that will best allow the board to fulfill its responsibilities.

The Board may utilize the services of a search firm to help identify candidates for director who meet the qualifications outlined above.

Stockholders may recommend individuals to the independent directors for consideration as potential director candidates by submitting their names, together with appropriate biographical information and background materials and a statement as to whether the stockholder or group of stockholders making the recommendation has beneficially owned more than 5% of our common stock for at least a year as of the date such recommendation is made, to Independent Directors, c/o Corporate Secretary, Grill Concepts, Inc., 11661 San Vicente Blvd., Suite 404, Los Angeles, California 90049. Assuming that appropriate biographical and background material has been provided on a timely basis, the stockholder-recommended candidates will be evaluated by following substantially the same process, and applying substantially the same criteria, as it follows for candidates recommended by our board or others. If the board determines to nominate a stockholder-recommended candidate and recommends his or her election, then his or her name will be included in the proxy card for the next annual meeting.

Stockholders also have the right under our bylaws to directly nominate director candidates, without any action or recommendation on the part of the board, by following the procedures set forth under “Deadline for Submission of Stockholder Proposals for the 2008 Annual Meeting” on page 25. Candidates nominated by stockholders in accordance with the procedures set forth in the bylaws will not be included in our proxy card for the next annual meeting.

Our board will give appropriate attention to written communications that are submitted by stockholders, and will respond if and as appropriate. Our lead director, Mr. Golenberg, is primarily responsible for monitoring communications from stockholders and for providing copies or summaries to the other directors as he considers appropriate.

Communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that the lead director, with the assistance of our counsel, considers to be important for the directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we tend to receive repetitive or duplicative communications.

Stockholders who wish to send communications on any topic to the board should address such communications to Grill Concepts, Inc. Board of Directors, c/o Corporate Secretary, Grill Concepts, Inc., 11661 San Vicente Blvd., Suite 404, Los Angeles, California 90049.

We have adopted a written code of conduct and ethics that applies to all our directors, officers and employees, including our chief executive officer and our chief financial and accounting officer. A current copy of the code can be found as an exhibit to our Annual Report on Form 10-K for the year ended December 28, 2003 as filed with the SEC on March 26, 2004, located at www.sec.gov. In addition, we intend to post on our website or file under cover of Form 8-K all disclosures that are required by law or Nasdaq listing standards concerning any amendments to, or waivers from, any provision of the code.

All members of the compensation committee are independent directors, and none of them are present or past employees or officers of ours or any of our subsidiaries. No member of the compensation committee has had any

22

relationship with us requiring disclosure under Item 404 of Regulation S-K under the Exchange Act. None of our executive officers has served on the board or compensation committee (or other committee serving an equivalent function) of any other entity.

In accordance with our audit committee charter, our audit committee is responsible for reviewing and approving the terms and conditions of all related party transactions. A report is made to our audit committee annually disclosing all related parties that are employed by us and related parties that are employed by other companies that we had a material relationship with during that year, if any.

The Company has entered into transactions with various entities that may be deemed to be controlled by Lewis Wolff. Mr. Wolff is the trustee of the Wolff Revocable Trust of 1993 that holds all of the outstanding preferred stock of the Company and may be deemed to be a controlling stockholder of the Company. Mr. Wolff served as director of the Company from June 2001 to June 2006. Transactions that provide for ongoing obligations and/or rights of the Company, or with respect to which amounts were paid during 2005 and/or 2006, or are expected to be paid, and which may be deemed to have been entered into with Mr. Wolff and his affiliates include: (1) lease of the site of the San Jose Grill at the San Jose Fairmont Hotel from an entity in which Mr. Wolff is a part owner, (2) entry into an agreement (the “HRP Agreement”) with Hotel Restaurant Properties, Inc. (“HRP”), an entity controlled by a member of Mr. Wolff’s family, pursuant to which HRP assisted the Company in locating hotel locations for the opening of restaurants and pursuant to which HRP was entitled to a portion of the fees or profits from those restaurants, and (3) entry into a Purchase Agreement in September 2006 pursuant to which the Company agreed to purchase, and HRP, Keith Wolff and certain related persons and entities agreed to sell, certain rights and interests in the HRP Agreement. Rents in the amount of $387,000 and $257,000 were accrued by the Company with respect to the San Jose Grill during 2006 and 2005, respectively.

In August 1998, the Company entered into an agreement with HRP, of which Mr. Keith Wolff is President. Pursuant to the agreement HRP agreed to assist the Company in locating hotel locations for the opening of restaurants. HRP was entitled to a portion of the fees or profits from those restaurants. The Company paid $214,000 and $423,000 of management fees to HRP during fiscal years 2006 and 2005, respectively. The agreement also provided that HRP would repay to the Company amounts advanced to manage units on behalf of HRP. As of December 31, 2006, HRP owed to the Company $0.

On September 1, 2006, the Company and certain affiliated entities, entered into an Agreement for Purchase and Sale of Assets (the “Purchase Agreement”) with HRP, Hotel Restaurant Properties II, Inc., Hotel Restaurant Properties II Management, Inc., Keith Wolff and Adam Keller (collectively, the “Sellers”).

Pursuant to the terms of the Purchase Agreement, the Sellers agreed to sell to the Company and the Company agreed to purchase from the Sellers certain rights and interests of the Sellers relating to the current and future operation of Company restaurants in hotel properties pursuant to the terms of the HRP Agreement. Under the terms of the HRP Agreement, the Sellers had the exclusive right to obtain hotel-based locations for Company restaurants and were entitled to receive a portion of the net income, management fees, licensing fees or similar fees of the Company from the operation of such hotel-based restaurants. The Company, at the date of the Purchase Agreement, operated seven restaurants subject to the HRP Agreement in Skokie, Illinois; San Francisco, California; Houston, Texas; Washington, D.C.; Burbank, California; Portland, Oregon; and Long Beach, California.

Under the Purchase Agreement, the Sellers agreed to transfer to the Company all of the rights in the management agreements (the “Transferred Agreements”) relating to the San Francisco, Houston, Washington, D.C. and Portland restaurants as well as ownership of the Houston liquor license.

23

Pursuant to the Purchase Agreement, the HRP Agreement was amended, effective June 30, 2006 (the “Effective Date”), to eliminate exclusivity provisions under which the Company would use the Sellers as the exclusive parties to identify potential hotel restaurant locations and to eliminate certain provisions under which the Sellers could cause the Company to purchase HRP and the Company could acquire HRP. Under the Purchase Agreement, the Sellers also agreed to relinquish any rights to fees or other compensation relating to Company restaurants opened in hotels pursuant to management, license or lease agreements entered on or after March 29, 2006, including any fees relating to restaurants proposed to be opened in Memphis, Tennessee and Seattle, Washington.

The Sellers will retain their rights in the management contracts relating to the Burbank, Skokie and Long Beach restaurants subject to the continuing terms of the HRP Agreement, as amended, and subject to the rights of the Company to terminate operations of the Skokie and Long Beach restaurants.

The purchase price of the acquired assets under the Purchase Agreement is $2,771,133 (the “Purchase Price”). Closing of the purchase and sale shall occur, and the Purchase Price is payable, on the earlier of June 30, 2007 (the “Outside Closing Date”) or a mutually agreeable date not more than 10 days after the date on which the aggregate payments (the “Income Stream Payments”) received by the Sellers, after the Effective Date and prior to closing, under the Transferred Agreements equal $294,151 (the “Maximum Income Stream Payments”). From and after the Effective Date the Income Stream Payments shall not exceed the Maximum Income Stream Payments after the payment of which no further payments shall be made to the Sellers with respect to the Transferred Agreements. In the event that the Sellers shall not have received the Maximum Income Stream Payments by the closing date, the Purchase Price shall be increased by the excess of the Maximum Income Stream Payments over the actual Income Stream Payments as of the closing date.

On the closing date, the HRP Agreement will be further amended to eliminate the license granted thereunder for the Sellers to operate managed outlets under the HRP Agreement, eliminate restrictions on the Sellers’ ability to provide similar hotel restaurant location services to parties other than the Company and to eliminate other provisions relating to the Transferred Agreements.

At closing, the Sellers shall enter into a Non-Competition Agreement pursuant to which the Sellers, for a period of 5 years from the closing date, will not assist any owner, operator, franchisor or franchisee of a branded restaurant in entering into a lease, license or management agreement to operate a restaurant, provide room service or provide food for banquet room events at any hotel (the “Restricted Business”), provided, however, that the Sellers shall not be prohibited from (i) owning up to 10% of any publicly traded company engaged in the Restricted Business, (ii) engaging in the Restricted Business with respect to hotel properties owned by the Sellers or affiliates of the Sellers and managed by the Sellers or the affiliates of the Sellers or (iii) engaging in the Restricted Business with up to 3 additional hotels. Branded restaurants, for purposes of the Non-Competition Agreement, mean a restaurant concept operated in ten or more locations under a single brand name.

Pursuant to the Purchase Agreement, the Company has agreed to indemnify the Sellers with respect to any additional tax that may be incurred, as well as related penalties and interest, in the event that the goodwill allocated to the sale is reduced for tax purposes on audit or other adjustment.

Closing of the purchase and sale is subject to satisfaction of various conditions, including delivery of the purchase price, execution and delivery of the Non-Competition Agreement, the delivery of all required consents, assignments, releases and other documents, the accuracy of representations and warranties, the absence of litigation contesting the transaction and other standard commercial conditions.

In July 2001, the Company completed a series of transactions with Starwood Hotels & Resorts Worldwide, Inc., pursuant to which (1) Starwood acquired, for $1,000,000.50, 666,667 shares of Common Stock and five

24

year $2.00 666,667 warrants to purchase shares of the Company’s Common Stock, (2) the Company and certain stockholders agreed to take appropriate actions, so long as Starwood owns no fewer than 333,333 shares of Common Stock, to cause one nominee of Starwood to be elected to the Company’s board or, in the event the number of restaurants operated pursuant to the Starwood Agreements equals or exceeds ten restaurants, to cause two nominees of Starwood to be elected to the Company’s board, and (3) the Company and Starwood agreed to jointly develop the Company’s branded restaurants in Starwood properties with Starwood being the exclusive major hotel operator in which the Company’s restaurants are developed, managed, operated or licensed. Richard Dantas was designated as Starwood’s board representative and currently serves as a Director of the Company.

The Starwood Agreements also provide for the issuance to Starwood, after the aggregate number of branded restaurants covered by management agreements or licensing agreements reaches five, ten, fifteen and twenty (each a “Development Threshold Date”), of warrants (the “Development Warrants”) to purchase a number of shares of the Company’s Common Stock equal to 4% of the then outstanding shares of capital stock. The Development Warrants will have an exercise price equal to (1) if the fair market value of the Common Stock as of the applicable Development Threshold Date is greater than the fair market value of the Common Stock as of the closing date of the transactions contemplated by the Starwood Agreements (the “Closing Date”), the greater of (A) 75% of the fair market value of the Common Stock on the date of issuance of the Development Warrants or (B) the fair market value of the Common Stock on the closing date as defined in the Starwood Agreements, or (2) if the fair market value of the Common Stock as of the applicable Development Threshold Date is equal to or less than the fair market value of the Common Stock on the closing date, the fair market value of the Common Stock as of the applicable Development Threshold Date.

In addition to the Development Warrants, the Starwood Agreements provide for the issuance of warrants (the “Incentive Warrants”) to Starwood to purchase a number of shares of the Company’s Common Stock equal to 0.75% of the then outstanding shares of capital stock of the Company on the date of execution of any management agreement or license agreement (the “Initial Incentive Threshold Date”) resulting in the total number of restaurants being operated pursuant to the Starwood Agreements exceeding 35% of the total branded restaurants operated by the Company. Additional Incentive Warrants will be issued on each anniversary of the Initial Incentive Threshold Date provided that the incentive threshold continues to be satisfied.

On June 21, 2006, the Company entered into a First Amendment to Development Agreement (the “First DA Amendment”) with Starwood. The First DA Amendment amended the Company’s July 27, 2001 Development Agreement with Starwood to (1) eliminate the Company’s obligation to issue warrants to Starwood following the opening of ten, fifteen and twenty restaurants under the terms of the Development Agreement and (2) modify the exercise price of warrants issued following the opening of five restaurants under the terms of the Development Agreement.

Under the terms of the amended Development Agreement, if a fifth restaurant is opened under the terms of the Development Agreement before April 1, 2008, the Company will issue to Starwood warrants to purchase a number of shares of common stock equal to 4% of the then outstanding shares. If the fifth restaurant is opened after April 1, 2008, the Company will issue to Starwood warrants to purchase a number of shares of common stock equal to 4% of the shares outstanding at December 25, 2005.

The warrants will have an exercise price equal to (1) if the fair market value of the common stock as of the date of issuance of the warrants (the “Threshold Date Value”) is greater than the fair market value of the common stock as of the date of the original Development Agreement (the “Closing Date Value”), the greater of (A) 75% of the Threshold Date Value, or (B) the Closing Date Value, or (2) if the Threshold Date Value of the common stock is less than the Closing Date Value, the Threshold Date Value.

Simultaneous with execution of the First DA Amendment, the Company entered into a First Amendment to Stockholders’ Agreement (the “First SA Amendment”) with Starwood. The First SA Amendment amends the July 27, 2001 Stockholders Agreement between the Company, Starwood and certain stockholders of the

25

Company to (1) eliminate the Company’s obligation to cause at least two nominees of Starwood to be elected to the Company’s board of directors if ten or more restaurants are operated under the Development Agreement, and (2) modify certain provisions limiting the size of the Company’s board of directors.

Under the terms of the amended Stockholders’ Agreement, so long as Starwood continues to hold at least 333,334 shares of Company common stock, the Company shall take all actions reasonably necessary to assure that at least one nominee of Starwood is elected to the board of directors and to limit the size of the board of directors to no more than 9 persons.

In March 2007, Starwood transferred all of its shares of our common stock to a separate entity, called Eaturna LLC, in which Starwood holds a non-controlling interest.

As described under Executive Compensation – Post-Employment Compensation, pursuant to the terms of the Employment Agreement of Robert Spivak and a Consulting Agreement with Mr. Spivak, upon Mr. Spivak’s retirement in December 2006, we retained Mr. Spivak as a consultant for a period of ten years following his retirement. Under the terms of that Consulting Agreement, we agreed to pay to Mr. Spivak $12,500 per month and Mr. Spivak agreed to provide an estimated 40 hours per month of services. Additionally, we agreed to provide to Mr. Spivak use of an office, a $1,000 per month restaurant meal allowance and continued medical, life and disability insurance and, for a period of 18 months, an automobile. Mr. Spivak continues to serve as a director.

In 1993, Michael Weinstock, Executive Vice President and Chairman of the Board, loaned $85,000 to the Company in an uncollateralized subordinated note, renewable annually with interest accruing at 7% per annum. The loan from Mr. Weinstock was repaid in full during fiscal 2006.

In 1998, Robert Spivak, a director and former President and Chief Executive Officer, loaned $70,000 to the Company in an uncollateralized subordinated note, renewable annually with interest accruing at 10% per annum. The loan from Mr. Spivak was repaid in full during fiscal 2006.

SECTION 16(a) BENEFICIAL OWNERSHIP

Section 16(a) of the Exchange Act, or “Section 16(a)”, requires that directors, executive officers and persons who own more than ten percent of any registered class of a company’s equity securities, or “reporting persons”, file with the SEC initial reports of beneficial ownership and report changes in beneficial ownership of common stock and other equity securities. Reporting persons holding our stock are required by SEC regulations to furnish us with copies of all Section 16(a) reports they file.

Based solely on our review of copies of these reports, and written representations from such reporting persons, we believe that all filings required to be made by reporting persons of our stock were timely filed for the year ended December 31, 2006 in accordance with Section 16(a).

RELATIONSHIP WITH INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The audit committee is responsible for assessing the information provided by management and our registered public accounting firm in accordance with its business judgment. Management is responsible for the preparation, presentation and integrity of our financial statements and for the appropriateness of the accounting principles and reporting policies that are used. Management is also responsible for testing the system of internal controls, and reports to the audit committee on any deficiencies found. Our registered public accounting firm, Moss Adams LLP, is responsible for auditing the financial statements and for reviewing the unaudited interim financial statements.

The audit committee reviewed with our registered public accounting firm the overall scope and plan of the audit. In addition, it met with our registered public accounting firm, with and without management present, to discuss the results of Moss Adams LLP’s examination, the overall quality of our financial reporting and such other matters as are required to be discussed under generally accepted auditing standards. The audit committee has also received from, and discussed with, our registered public accounting firm the matters required to be discussed by Statement on Auditing Standards 61 (Communication with Audit Committees).

The audit committee has discussed with Moss Adams LLP that firm’s independence from management and our company, including the matters in the written disclosures and the letter required by the Independence Standards Board Standard No. 1. The audit committee has also considered the compatibility of audit related and tax services with the auditors’ independence.

In fulfilling its oversight responsibilities, the audit committee has reviewed and discussed the audited financial statements in the Annual Report on Form 10-K for the year ended December 31, 2006 with both management and our registered public accounting firm. The audit committee’s review included a discussion of the quality and integrity of the accounting principles, the reasonableness of significant estimates and judgments, and the clarity of disclosures in the financial statements.

In reliance on the reviews and discussions referred to above, the audit committee recommended to the board, and the board has approved, that the audited financial statements be included in the Annual Report on Form 10-K for the year ended December 31, 2006 for filing with the SEC. The audit committee has recommended to the board the reappointment of Moss Adams LLP as our registered public accounting firm for the 2007 fiscal year.

By the Audit Committee of the Board of Directors:

Glenn Golenberg, Audit Committee Chair

Stephen Ross, Audit Committee Member

Bruce Schwartz, Audit Committee Member

27

The following table summarizes the fees of Moss Adams LLP, our registered public accounting firm, and PricewaterhouseCoopers, our prior registered public accounting firm, billed to us for each of the last two fiscal years:

The audit committee has adopted policies and procedures relating to the approval of all audit and non-audit services that are to be performed by our registered public accounting firm. This policy generally provides that we will not engage our registered public accounting firm to render audit or non-audit services unless the service is specifically approved in advance by the audit committee or the engagement is entered into pursuant to one of the pre-approval procedures described below.

From time to time, the audit committee may pre-approve specific types of services that are expected to be provided by our registered public accounting firm during the next 12 months. Any such pre-approval is detailed as to the particular services to be provided and is also generally subject to a maximum dollar amount.

The committee’s practice is to consider for approval, at its regularly scheduled quarterly meetings, all audit and non-audit services proposed to be provided by our registered public accounting firm. In situations where a matter cannot wait until the next regularly scheduled committee meeting, the chairman of the committee has been delegated authority to consider and, if appropriate, approve audit and non-audit services or, if in the chairman’s judgment it is considered appropriate, to call a special meeting of the committee for that purpose.

Some banks, brokers and other nominee record holders may be participating in the practice of “householding”. This means that only one copy of our annual report and proxy statement will be sent to stockholders who share the same last name and address. Householding is designed to reduce duplicate mailings and save significant printing and postage costs.

If you receive a household mailing this year and would like to receive additional copies of our annual report and/or proxy statement, please submit your request in writing to: Grill Concepts, Inc., 11661 San Vicente Blvd., Suite 404, Los Angeles, California 90049, Attention: Secretary or by calling Grill Concepts at (310) 820-5559. Any stockholder who wants to receive separate copies of the proxy statement in the future, or who is currently receiving multiple copies and would like to receive only one copy for his or her household, should contact his or her bank, broker, or other nominee record holder.

28

DEADLINE FOR SUBMISSION OF STOCKHOLDER PROPOSALS

Any stockholders who wish to submit a proposal, pursuant to Rule 14a-8 under the Exchange Act, for inclusion in the proxy materials for our 2008 annual meeting of stockholders must ensure that it is received by our corporate secretary at our corporate headquarters, which are located at 11661 San Vicente Blvd., Suite 404, Los Angeles, California 90049, no later than January 4, 2008.

Our amended and restated by-laws also establish an advance notice procedure for stockholders who wish to nominate candidates for election as directors. We must receive a notice regarding stockholder nominations for director at our corporate headquarters not less than 60 days nor more than 90 days prior to the applicable stockholder meeting, provided, however, that in the event we do not publicly announce the date of the applicable annual meeting by mail, press release or otherwise more than 70 days prior to the meeting, we must receive the notice no later than the tenth day following the day on which such announcement of the date of the meeting is made. Any such notice must contain certain specified information concerning the persons to be nominated and the stockholder submitting the nomination, all as set forth in the amended and restated by-laws. The presiding officer of the meeting may refuse to acknowledge any director nomination not made in compliance with such advance notice requirements. We have not publicly announced the date of the 2007 annual meeting prior to the mailing of this notice and proxy statement. Accordingly, an appropriate notice from a stockholder regarding nominations for director to be acted on at the 2007 annual meeting must be received within ten days of this mailing.

By Order of the Board of Directors,

MICHAEL WEINSTOCK

Chairman

THE BOARD ENCOURAGES STOCKHOLDERS TO ATTEND THE ANNUAL MEETING. WHETHER OR NOT YOU PLAN TO ATTEND, YOU ARE URGED TO COMPLETE, DATE, SIGN AND RETURN THE ENCLOSED PROXY IN THE ACCOMPANYING ENVELOPE. A PROMPT RESPONSE WILL GREATLY FACILITATE ARRANGEMENTS FOR THE ANNUAL MEETING AND YOUR COOPERATION WILL BE APPRECIATED. STOCKHOLDERS WHO ATTEND THE ANNUAL MEETING MAY VOTE THEIR STOCK PERSONALLY EVEN THOUGH THEY HAVE SENT IN THEIR PROXIES.
