	1. The Company and Summary of Significant Accounting Policies
	Description of Business
	BJ’s Restaurants, Inc. (referred to herein as the “Company” or “BJ’s” or in the first person notations “we,” “us” and “our”) was incorporated in California on October 1, 1991, to assume the management of five “BJ’s Chicago Pizzeria” restaurants then in existence and to develop additional BJ’s restaurants. As of December 31, 2013, we owned and operated 146 restaurants located in 17 states (California, Texas, Florida, Arizona, Colorado, Nevada, Ohio, Washington, Oklahoma, Oregon, Kentucky, Virginia, Indiana, Kansas, Louisiana, Maryland and New Mexico). Each of our restaurants is currently operated as a BJ’s Restaurant & Brewery®, BJ’s Restaurant & Brewhouse®, BJ’s Pizza & Grill® or BJ’s Grill®. During fiscal 2013, we opened 17 new restaurants. Four of our locations brew our signature, proprietary craft BJ’s beer on the restaurant premises. All of our other restaurants receive their BJ’s beer either from one of these four “brewery” locations and/or independent third party brewers.
	Basis of Presentation
	The accompanying consolidated financial statements include the accounts of BJ’s Restaurants, Inc. and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. The financial statements presented herein include all material adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair statement of the financial condition, results of operations and cash flows for the period.
	The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make estimates and assumptions for the reporting period and as of the financial statement date. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual results could differ from those estimates.
	Our fiscal year consists of 52 or 53 weeks and ends on the Tuesday closest to December 31 for financial reporting purposes. Fiscal year 2013 and fiscal year 2012 ended on December 31, 2013 and January 1, 2013, respectively, and consisted of 52 weeks of operations. Fiscal year 2011 ended on January 3, 2012 and consisted of 53 weeks of operations.
	Segment Disclosure
	Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic No. 280, Segment Reporting, establishes standards for disclosures about products and services, geographic areas and major customers. We currently operate in one operating segment: casual dining restaurants, four of which have on-premise brewing operations that produce BJ’s signature, proprietary craft beers for our restaurants. Additionally, we operate in one geographic area: the United States of America.
	Cash and Cash Equivalents
	Cash and cash equivalents consist of highly liquid investments and money market funds with an original maturity of three months or less when purchased. Cash and cash equivalents are stated at cost, which approximates fair market value.
	Investments in Marketable Securities
	Our investment policy restricts the investment of our excess cash balances to instruments with minimal volatility, such as money market funds, U.S. Treasury and direct agency obligations, municipal and bank securities and investment-grade corporate debt securities. Marketable securities, which we have the intent and ability to hold until maturity, are classified as held-to-maturity securities and reported at amortized cost with related gains and losses reflected in earnings. Marketable securities in the form of debt securities are classified as available-for-sale securities and reported at their fair value, with unrealized gains and losses excluded from net income and reported as a separate component of shareholders’ equity (net of related tax effect) until realized. Any fluctuation in fair value related to investments that are deemed temporary, including any recoveries of previous write-downs, are recorded to accumulated other comprehensive income. Realized gains or losses are determined on the specific identification cost method and recorded as a charge to earnings, when realized.
	As of December 31, 2013 and January 1, 2013, our investments in marketable securities were classified in the held-to-maturity or available-for-sale categories.
	Concentration of Credit Risk
	Financial instruments which potentially subject us to a concentration of credit risk principally consist of cash and cash equivalents, investments and marketable securities. We currently maintain our day-to-day operating cash balances with a major financial institution. At times, our operating cash balances may be in excess of the FDIC insurance limit. At December 31, 2013, we had approximately $9.8 million of investments in marketable securities, of which $0.1 million were considered cash and cash equivalents, held by institutional brokers. We have placed a majority of our temporary excess cash with major financial institutions and institutional brokers that, in turn, invests in instruments with expected minimal volatility, such as money market funds, U.S. Treasury and direct agency obligations, municipal and bank securities and investment-grade corporate debt securities. Our investment policy limits the amount of exposure to any one institution or investment. We did not experience any losses in these accounts during fiscal 2013, 2012 or 2011, and believe we are not exposed to significant risk on cash and cash equivalents.
	Inventories
	Inventories are comprised primarily of food and beverage products and are stated at the lower of cost (first-in, first-out) or market.
	Property and Equipment
	Property and equipment are recorded at cost and depreciated over their estimated useful lives. Leasehold improvements are amortized over the estimated useful life of the asset or the primary lease term of the respective lease including exercised options, whichever is shorter. Renewals and betterments that materially extend the life of an asset are capitalized while maintenance and repair costs are expensed as incurred. When property and equipment are sold or otherwise disposed of, the asset account and related accumulated depreciation or amortization accounts are relieved, and any gain or loss is included in earnings.
	Depreciation and amortization are recorded using the straight-line method over the following estimated useful lives:
	Furniture and fixtures	10 years
	Equipment	5-10 years
	Brewery equipment	10-20 years
	Building improvements	the shorter of 20 years or the remaining lease term
	Leasehold improvements	the shorter of the useful life or the lease term
	Goodwill and Intangible Assets
	We perform impairment testing annually, during the fourth quarter, and more frequently if factors and circumstances indicate an impairment may have occurred. When evaluating goodwill for impairment, we first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, we calculate the implied estimated fair value of the reporting unit and compare it to the carrying value of the goodwill. If the carrying value of the goodwill is greater than the implied estimated fair value, an impairment charge is recorded to reduce the carrying value to the implied estimated fair value. This adjusted carrying value becomes the new goodwill accounting basis value.
	Definite-lived intangible assets are amortized over their estimated useful lives and tested for impairment when facts and circumstances indicate that the carrying values may not be recoverable. Trademarks with indefinite lives are amortized over 10 years and tested for impairment when facts and circumstances indicate that the carrying values may not be recoverable. We believe that no impairments of goodwill and intangible occurred during fiscal 2013, 2012, or 2011.
	Long-Lived Assets
	We assess potential impairments of our long-lived assets whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. The assets are generally reviewed for impairment in total as well as on a restaurant by restaurant basis. Factors considered include, but are not limited to, significant underperformance by the restaurant relative to expected historical or projected future operating results, significant changes in the manner of use of the acquired assets or the strategy for the overall business, and significant negative industry or economic trends. The recoverability is assessed in most cases by comparing the carrying value of the asset to the undiscounted cash flows expected to be generated by the asset. This assessment process requires the use of estimates and assumptions regarding future restaurant cash flows and estimated useful lives, which are subject to a significant degree of judgment. If these assumptions change in the future, we may be required to record impairment charges for these assets or for the entire restaurant. If the carrying amount is greater than the anticipated undiscounted cash flows, an impairment charge is recorded as the difference between the carrying amount and the assets fair value. In fiscal 2013, we recorded impairment expense of $3.1 million, which is included in “Loss on disposal of assets and impairments” in the Consolidated Statement of Income, representing a reduction in the carrying value of one of our underperforming BJ’s Restaurant & Brewhouse® restaurants. There was no long-lived asset impairment recorded during fiscal year 2012 or 2011.
	Revenue Recognition
	Revenues from food and beverage sales at restaurants are recognized when payment is tendered at the point-of-sale. Revenues from the sale of gift cards are deferred and recognized upon redemption. Deferred gift card revenue, included in “Accrued expenses” on the accompanying Consolidated Balance Sheets, was $7.8 million and $7.2 million as of December 31, 2013 and January 1, 2013, respectively. We recognize gift card breakage income when the likelihood of the redemption of the cards becomes remote, which is typically 24 months after original issuance. Gift card breakage income is recorded in “Other income, net” on the Consolidated Statements of Income.
	Customer Loyalty Program
	In July 2012, we introduced “BJ’s Premier Rewards” customer loyalty program to all of our restaurants. This program enables participants to earn points for each qualifying purchase. The points can then be redeemed for rewards including food discounts, trips, events and other items. We measure our total rewards obligation based on the estimated number of customers that will ultimately earn and claim rewards under the program, and record the estimated related expense as reward points accumulate. These expenses are accrued for and recorded as marketing expenses and are included in “Occupancy and operating” expenses on our Consolidated Statements of Income.
	Sales Taxes
	Revenues are presented net of sales taxes. The obligation is included in other accrued expenses until the taxes are remitted to the appropriate taxing authorities.
	Advertising Costs
	Advertising costs are expensed as incurred. Advertising expense for fiscal 2013, 2012, and 2011 was approximately $17.1 million, $10.6 million, and $7.2 million, respectively.
	Income Taxes
	We provide for income taxes based on our estimate of federal and state tax liabilities. Our estimates include, but are not limited to, effective state and local income tax rates, allowable tax credits for items such as FICA taxes paid on reported tip income and estimates related to depreciation expense allowable for tax purposes. We usually file our income tax returns several months after our fiscal year-end. We file our tax returns with the advice and compilation of tax consultants. All tax returns are subject to audit by federal and state governments, usually years after the returns are filed, and could be subject to differing interpretation of the tax laws.
	We utilize the liability method of accounting for income taxes. Deferred income taxes are recognized based on the tax consequences in future years of differences between the tax basis of assets and liabilities and their financial reporting amounts at each year-end based on enacted tax laws and statutory tax rates applicable to the periods in which differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. The provision for income taxes represents the tax payable for the period and the change during the period in deferred tax assets and liabilities.
	We recognize the impact of a tax position in our financial statements if that position is more likely than not of being sustained on audit, based on the technical merits of the position. Interest and penalties related to uncertain tax positions are included in income tax expense.
	Restaurant Opening Expense
	Restaurant payroll, supplies, training, other start-up costs and rent expense incurred prior to the opening of a new restaurant are expensed as incurred.
	Legal and Other Settlements
	Legal settlements primarily relate to the proposed settlements of certain California employment practices lawsuits and alleged trademark infringements. We agreed to these settlements, which are subject to court approval, in order to avoid the costs, risks and uncertainties inherent in litigation and to eliminate the further diversion of our management’s time and attention, and without admitting any liability on our part. Other settlements relate to an employment separation, a Texas Alcoholic Beverage Commission settlement related to our beer model, and a California sales tax audit assessment.
	Investment Settlement
	In December 2009, we agreed to a settlement with our former broker-dealer for the full liquidation of our auction rate securities (“ARS”) investment portfolio. Under the terms of the settlement agreement, we were entitled to potential future recoveries of our loss on that portfolio based on the performance of those auction rate securities through December 2012. We received recoveries of approximately $0.8 million and $0.6 million for fiscal 2012 and 2011, respectively.
	Leases
	We lease the majority of our restaurant locations. We account for our leases in accordance with U.S. GAAP, which require that our leases be evaluated and classified as operating or capital leases for financial reporting purposes. The term used for this evaluation includes renewal option periods only in instances in which the exercise of the renewal option can be reasonably assured and failure to exercise such option would result in an economic penalty. All of our restaurant leases are classified as operating leases. We disburse cash for leasehold improvements, furniture and fixtures and equipment to build out and equip our leased premises. Tenant improvement allowance incentives may be available to partially offset the cost of developing and opening the related restaurants, pursuant to agreed-upon terms in our leases. Tenant improvement allowances can take the form of cash payments upon the opening of the related restaurants, full or partial credits against minimum or percentage rents otherwise payable by us or a combination thereof. All tenant improvement allowances received by us are recorded as a deferred lease incentive and amortized over the term of the lease. The related cash received from the landlord is reflected as “Landlord contribution for tenant improvements, net” within operating activities of our Consolidated Statements of Cash Flows.
	The lease term used for straight-line rent expense is calculated from the date we obtain possession of the leased premises through the lease termination date. We expense rent from possession date through restaurant open date as preopening expense. Once a restaurant opens for business, we record straight-line rent over the lease term plus contingent rent to the extent it exceeded the minimum rent obligation per the lease agreement.
	There is potential for variability in the rent holiday period, which begins on the possession date and ends on the restaurant open date, during which no cash rent payments are typically due under the terms of the lease. Factors that may affect the length of the rent holiday period generally relate to construction related delays. Extension of the rent holiday period due to delays in restaurant opening will result in greater preopening rent expense recognized during the rent holiday period and lesser occupancy expense during the rest of the lease term (post-opening).
	For leases that contain rent escalations in which the amount of future rent is certain or can be reasonably calculated, we record the total rent payable during the lease term, as determined above, on the straight-line basis over the term of the lease (including the rent holiday period beginning upon our possession of the premises), and record the difference between the minimum rents paid and the straight-line rent as deferred rent. Certain leases contain provisions that require additional rent payments based upon restaurant sales volume (“contingent rent”). Contingent rent is accrued each period as the liabilities are incurred, in addition to the straight-line rent expense noted above. This results in some variability in occupancy expense as a percentage of revenues over the term of the lease in restaurants where we pay contingent rent.
	Management makes judgments regarding the probable term for each restaurant property lease, which can impact the classification and accounting for a lease as capital or operating, the rent holiday and/or escalations in payments that are taken into consideration when calculating straight-line rent and the term over which leasehold improvements for each restaurant are amortized. These judgments may produce materially different amounts of depreciation, amortization and rent expense than would be reported if different assumed lease terms were used.
	Fair Value of Financial Instruments
	The carrying value of cash and cash equivalents, investments classified as held-to-maturity or available-for-sale or other current assets, accounts receivable and current liabilities approximate fair values due to the short-term maturity of these instruments. Investments classified as non-current assets are recorded at fair value based on valuation models and methodologies provided by a third party using either “Level 2” or “Level 3” inputs when the fair value of the investment cannot be determined based on current trades on the open market. Temporary changes in fair value of available-for-sale securities results in unrealized holding gains and losses being recorded in the “Other comprehensive income” component of shareholders’ equity and does not affect net income for the applicable accounting period. Declines in fair value below our carrying value deemed to be other than temporary are charged against net earnings.
	Net Income Per Share
	Basic net income per share is computed by dividing the net income attributable to common shareholders by the weighted average number of common shares outstanding during the period. Diluted net income per share reflects the potential dilution that could occur if stock options issued by us to sell common stock at set prices were exercised and if restrictions on restricted stock units issued by us were to lapse (collectively, equity awards). The consolidated financial statements present basic and diluted net income per share. Common stock equivalents included in the diluted computation represent shares to be issued upon assumed exercises of outstanding stock options and the assumed lapsing of the restrictions on restricted stock units using the treasury stock method.
	The following table presents a reconciliation of basic and diluted net income per share computations and the number of dilutive equity awards (stock options and restricted stock units) that were included in the dilutive net income per share computation (in thousands):

Stock-Based Compensation
Under shareholder approved stock-based compensation plans, we have granted incentive stock options, non-qualified stock options and restricted stock units that generally vest over five years and expire ten years from the date of grant. Stock-based compensation is measured in accordance with U.S. GAAP based on the underlying fair value of the awards granted. In valuing stock options, we are required to make certain assumptions and judgments regarding the grant date fair value utilizing the Black-Scholes option-pricing model. These judgments include expected volatility, risk free interest rate, expected option life, dividend yield and vesting percentage. These estimations and judgments are determined by us using many different variables that, in many cases, are outside of our control. The changes in these variables or trends, including stock price volatility and risk free interest rate, may significantly impact the grant date fair value resulting in a significant impact to our financial results. The cash flow tax benefits resulting from tax deductions in excess of the compensation cost recognized for those options (excess tax benefits) are required to be classified as financing cash flows.

	2. Marketable Securities
	Our investment policy restricts the investment of our excess cash balances to instruments with historically minimal volatility, such as money market funds, U.S. Treasury and direct agency obligations, municipal and bank securities, and investment-grade corporate debt securities. All highly liquid investments with maturities of three months or less at the date of purchase are classified as cash equivalents and included with “Cash and cash equivalents” on our accompanying Consolidated Balance Sheets. Marketable securities, which we have the intent and ability to hold until maturity, are classified as held-to-maturity securities and reported at amortized cost, which approximates fair value. Marketable securities, in the form of municipal variable rate demand notes with expected put dates prior to the contractual maturity of the underlying debt security and backed by financial institutions in the form of a letter of credit or liquidity facility, are classified as available-for-sale securities. These securities are reported at fair value, using a market approach and classified as Level 2 fair value measurements, as further described in Note 3. Any unrealized gains or losses on available-for-sale securities would be recorded in other comprehensive income. As of December 31, 2013 and January 1, 2013, there were no unrealized gains or losses with respect to available-for-sale securities.
	We determine the appropriate classification of our marketable securities at the time of purchase and reevaluate the held-to-maturity or available-for-sale designations as of each balance sheet date. Marketable securities are classified as either short-term or long-term based on each instrument’s underlying contractual maturity date or the expected put date. Marketable securities with maturities or expected put dates of 12 months or less are classified as short-term and marketable securities with maturities or expected put dates greater than 12 months are classified as long-term. Gains or losses are determined on the specific identification cost method and recorded in earnings when realized.

Fair Value Measurement	'
	3. Fair Value Measurement
	In accordance with U.S. GAAP, a framework for using fair value to measure assets and liabilities was established by defining a three-tier fair value hierarchy, which prioritizes the inputs used to measure fair value. These tiers include:
		•	Level 1: Defined as observable inputs such as quoted prices in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.
		•	Level 2: Defined as pricing inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors, and current market and contractual prices for the underlying instruments, as well as other relevant economic measures.
		•	Level 3: Defined as pricing inputs that are generally less observable from objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value.
	At December 31, 2013, we had approximately $32.8 million of cash and cash equivalents and marketable securities. Our marketable securities are held by institutional brokers, classified as held-to-maturity securities and reported at amortized cost, which approximates fair value (effectively, Level 2), or variable rate demand notes classified as available-for-sale securities and reported at fair value. We have placed a majority of our temporary excess cash with major financial institutions and institutional brokers that, in turn, invest in instruments with historically minimal volatility, such as money market funds, U.S. Treasury and direct agency obligations, municipal and bank securities, and investment-grade corporate debt securities. Our investment policy limits the amount of exposure to any one institution or investment. We have not experienced any losses on these marketable securities to date, and we believe that we are not exposed to significant risk of loss on these marketable securities.

	Leases
	We lease our restaurant and office facilities under noncancelable operating leases with remaining terms ranging from approximately 1 to 20 years with renewal options ranging from 5 to 20 years. Rent expense for fiscal 2013, 2012, and 2011 was $32.8 million, $29.7 million, and $26.1 million, respectively.
	We have certain operating leases that contain fixed rent escalation clauses. Rent expense for these leases has been calculated on the straight-line basis over the term of the leases, resulting in deferred rent of approximately $22.3 million and $18.6 million at December 31, 2013 and January 1, 2013, respectively. The deferred rent is presented on the accompanying Consolidated Balance Sheets and will be amortized to rent expense over the life of the leases.
	A number of the leases also provide for contingent rent based on a percentage of sales above a specified minimum. Total contingent rent, included in rent expense, above the minimum, for fiscal 2013, 2012, and 2011 were approximately $3.6 million, $4.4 million, and $4.0 million, respectively.
	Future minimum annual rent payments under noncancelable operating leases are as follows (in thousands):
	2014		$33,463
	2015		33,268
	2016		32,888

	Additionally, we have entered into lease agreements related to the construction of future restaurants with commencement dates subsequent to December 31, 2013. Our aggregate future commitment relating to these leases is $23.2 million.
	Legal Proceedings
	We are subject to private lawsuits, administrative proceedings and demands that arise in the ordinary course of our business and which typically involve claims from customers, employees and others related to operational, employment, real estate and intellectual property issues common to the foodservice industry. A number of these claims may exist at any given time. We are self-insured for a portion of our general liability insurance and our employee workers’ compensation programs. We maintain coverage with a third party insurer to limit our total exposure for these programs. We believe that most of our customer claims will be covered by our general liability insurance, subject to coverage limits and the portion of such claims that are self-insured. Punitive damages awards and employee unfair practice claims, however, are not covered by our general liability insurance. To date, we have not been ordered to pay punitive damages with respect to any claims, but there can be no assurance that punitive damages will not be awarded with respect to any future claims. We could be affected by adverse publicity resulting from allegations in lawsuits, claims and proceedings, regardless of whether these allegations are valid or whether we are ultimately determined to be liable. We currently believe that the final disposition of these types of lawsuits, proceedings and claims will not have a material adverse effect on our financial position, results of operations or liquidity. It is possible, however, that our future results of operations for a particular quarter or fiscal year could be impacted by changes in circumstances relating to lawsuits, proceedings or claims.
	Letters of Credit
	We have irrevocable standby letters of credit outstanding as required under our workers’ compensation insurance arrangements that total $12.1 million as of December 31, 2013, which automatically renew each October 31 for one year unless 30 days’ notice, prior to such renewal date, is given by the financial institution that provides the letters. The standby letters of credit have been issued under our credit facility and therefore reduce the amount available for borrowing under that facility.
	Other Commitments
	We have severance and employment agreements with certain of our executive officers that provide for payments to those officers in the event of a termination of their employment as a result of a change in control of the Company, or without cause, as defined in those agreements. Aggregate payments totaling approximately $2.8 million would have been required by those agreements had all such officers terminated their employment for those reasons as of December 31, 2013. Additionally, our future estimated cash payments under existing contractual purchase obligations for goods and services as of December 31, 2013 are approximately $6.2 million.

The Line of Credit expires on January 31, 2017, and may be used for working capital and other general corporate purposes. We utilize the Line of Credit principally for letters of credit that are required to support certain self-insurance programs and for working capital and construction requirements as needed. As of December 31, 2013, there were no funded borrowings outstanding under the Line of Credit and there were outstanding letters of credit totaling approximately $12.1 million. The Line of Credit bears interest at either LIBOR plus a percentage not to exceed 1.50%, or at a rate ranging from the financial institution’s prime rate to 0.75% below the financial institution’s prime rate based on a Lease Adjusted Leverage Ratio as defined in the Line of Credit agreement. The Line of Credit agreement requires compliance with a Fixed Charge Coverage Ratio, a Lease Adjusted Leverage Ratio and certain non-financial covenants. At December 31, 2013, we were in compliance with these covenants.

	10. Stock-Based Compensation Plans
	We have two stock-based compensation plans — the 2005 Equity Incentive Plan and the 1996 Stock Option Plan — under which we may issue shares of our common stock to employees, officers, directors and consultants. Upon effectiveness of the 2005 Equity Incentive Plan (the “Plan”), the 1996 Stock Option Plan was closed for purposes of new grants. Both of these plans have been approved by our shareholders. Under the Plan, we have granted incentive stock options, non-qualified stock options, and restricted stock units (“RSUs”). Shares subject to stock options and stock appreciation rights are charged against the Plan share reserve on the basis of one share for each one share granted while shares subject to other types of awards, including restricted stock units, are currently charged against the Plan share reserve on the basis of 1.5 shares for each one share granted. The Plan also contains other limits with respect to the terms of different types of incentive awards and with respect to the number of shares subject to awards that can be granted to an employee during any fiscal year. All options granted under the Plan expire within 10 years of their date of grant.
	Under the Plan, we issue RSUs as a component of the annual equity grant award to officers and other employees and in connection with the BJ’s Gold Standard Stock Ownership Program (the “GSSOP”). The GSSOP is a longer-term equity incentive program that utilizes Company RSUs or stock options and is dependent on each participant’s extended service with us in their respective positions and remaining in good standing during that service period (i.e., five years).
	The Plan permits us to set the vesting terms and exercise period for awards at our discretion. Stock options generally vest at 20% per year or cliff vest, either ratably in years three through five or 100% in year five, and expire ten years from date of grant. RSUs generally vest at 20% per year for non-GSSOP RSU grantees and generally cliff vest either at 33% on the third anniversary and 67% on the fifth anniversary or at 100% after the fifth anniversary for GSSOP participants.
	The following table presents information related to stock-based compensation (in thousands):
			Fiscal Year

	Capitalized stock-based compensation (1)			$215			$195		$187
	-1	Capitalized stock-based compensation is included in “Property and equipment, net” on the Consolidated Balance Sheets.
	Stock Options
	The fair value of each stock option grant issued is estimated at the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions:
			Fiscal Year
			2013			2012		2011
	Expected volatility			36.5%			36.74%		39.16%
	Risk free interest rate			0.76%			0.69%		1.80%
	Expected option life			5 years			5 years		5 years
	Dividend yield			0%			0%		0%
	Fair value of options granted			$11.04			$12.38		$14.37
	U.S. GAAP requires us to make certain assumptions and judgments regarding the grant date fair value. These judgments include expected volatility, risk free interest rate, expected option life, dividend yield and vesting percentage. These estimations and judgments are determined by us using many different variables that, in many cases, are outside of our control. The changes in these variables or trends, including stock price volatility and risk free interest rate, may significantly impact the grant date fair value resulting in a significant impact to our financial results.
	The exercise price of the stock options under our stock-based compensation plans shall be equal to or exceed 100% of the fair market value of the shares at the date of option grant. The following table represents stock option activity:

The fair value of each RSU is expensed over the period during which the restrictions are expected to lapse (i.e., five years). As of December 31, 2013, total unrecognized stock-based compensation expense related to non-vested restricted shares was approximately $7.9 million, which is generally expected to be recognized over the next five years.

Employee Benefit Plans	'
	11. Employee Benefit Plans
	We maintain a voluntary, contributory 401(k) plan for all eligible employees. Employees may elect to contribute up to 100% of their earnings, up to the IRS maximum for the plan year of participation. Additionally, eligible participants may also elect allowable catch-up contributions as provided for by the IRS. Our executive officers and other highly compensated employees are not eligible to participate in the 401(k) plan. Employee contributions are matched by us at a rate of 33% for the first 6% of deferred earnings. We contributed approximately $0.3 million, $0.3 million, and $0.2 million in fiscal 2013, 2012, and 2011, respectively.
	We also maintain a non-qualified deferred compensation plan (the “DCP”) for our executive officers and other highly compensated employees, as defined in the DCP who are otherwise ineligible for participation in our 401(k) plan. The DCP allows participating employees to defer the receipt of a portion of their base compensation and up to 100% of their eligible bonuses. Additionally, the DCP allows for a voluntary company match as determined by the Company’s compensation committee. During fiscal 2013, there were no contributions made or accrued by us. We pay for related administrative costs, which were not significant during fiscal 2013. Employee deferrals are deposited into a rabbi trust and the funds are generally invested in individual variable life insurance contracts owned by us that are specifically designed to informally fund savings plans of this nature. Our investment in variable life insurance contracts is reflected in “Other assets, net” on our Consolidated Balance Sheets. Our obligation to participating employees, included in “Other liabilities” on the accompanying Consolidated Balance Sheets, was $3.3 million and $2.1 million as of December 31, 2013 and January 1, 2013, respectively. All income and expenses related to the rabbi trust are reflected in our Consolidated Statements of Income.

	As of December 31, 2013, we believe that Jacmar Companies and their affiliates (collectively referred to herein as “Jacmar”) owned approximately 11.2% of our outstanding common stock. In addition, James Dal Pozzo, the Chief Executive Officer of Jacmar, is a member of our Board of Directors. Jacmar, through its affiliation with DMA is currently our largest supplier of food, beverage, paper products and supplies. We began using DMA for our national foodservice distribution in July 2006. In July 2012, we finalized a new five-year agreement with DMA, after conducting another extensive competitive bidding process. Jacmar services our restaurants in California and Nevada, while other DMA distributors service our restaurants in all other states. We also understand that Jacmar and its affiliates are the controlling shareholders of the Shakey’s pizza parlor chain. We believe that Jacmar sells products to us at prices comparable to those offered by unrelated third parties based on our competitive bidding process. Jacmar supplied us with $82.8 million, $78.0 million, and $68.0 million of food, beverage, paper products and supplies for fiscal 2013, 2012, and 2011, respectively, which represents 22.6%, 23.9%, and 24.3% of our total costs of sales and operating and occupancy costs, respectively. We had trade payables related to these products of $4.8 million and $3.7 million, at December 31, 2013 and January 1, 2013, respectively. Jacmar does not provide us with any produce, liquor, wine or beer products, all of which are provided by other vendors and are included in total cost of sales.

Description of Business	'
	Description of Business
	BJ’s Restaurants, Inc. (referred to herein as the “Company” or “BJ’s” or in the first person notations “we,” “us” and “our”) was incorporated in California on October 1, 1991, to assume the management of five “BJ’s Chicago Pizzeria” restaurants then in existence and to develop additional BJ’s restaurants. As of December 31, 2013, we owned and operated 146 restaurants located in 17 states (California, Texas, Florida, Arizona, Colorado, Nevada, Ohio, Washington, Oklahoma, Oregon, Kentucky, Virginia, Indiana, Kansas, Louisiana, Maryland and New Mexico). Each of our restaurants is currently operated as a BJ’s Restaurant & Brewery®, BJ’s Restaurant & Brewhouse®, BJ’s Pizza & Grill® or BJ’s Grill®. During fiscal 2013, we opened 17 new restaurants. Four of our locations brew our signature, proprietary craft BJ’s beer on the restaurant premises. All of our other restaurants receive their BJ’s beer either from one of these four “brewery” locations and/or independent third party brewers.
Basis of Presentation	'
	Basis of Presentation
	The accompanying consolidated financial statements include the accounts of BJ’s Restaurants, Inc. and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. The financial statements presented herein include all material adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair statement of the financial condition, results of operations and cash flows for the period.
	The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make estimates and assumptions for the reporting period and as of the financial statement date. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual results could differ from those estimates.
	Our fiscal year consists of 52 or 53 weeks and ends on the Tuesday closest to December 31 for financial reporting purposes. Fiscal year 2013 and fiscal year 2012 ended on December 31, 2013 and January 1, 2013, respectively, and consisted of 52 weeks of operations. Fiscal year 2011 ended on January 3, 2012 and consisted of 53 weeks of operations.
Segment Disclosure	'
	Segment Disclosure
	Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic No. 280, Segment Reporting, establishes standards for disclosures about products and services, geographic areas and major customers. We currently operate in one operating segment: casual dining restaurants, four of which have on-premise brewing operations that produce BJ’s signature, proprietary craft beers for our restaurants. Additionally, we operate in one geographic area: the United States of America.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	Cash and cash equivalents consist of highly liquid investments and money market funds with an original maturity of three months or less when purchased. Cash and cash equivalents are stated at cost, which approximates fair market value.
Investments in Marketable Securities	'
	Investments in Marketable Securities
	Our investment policy restricts the investment of our excess cash balances to instruments with minimal volatility, such as money market funds, U.S. Treasury and direct agency obligations, municipal and bank securities and investment-grade corporate debt securities. Marketable securities, which we have the intent and ability to hold until maturity, are classified as held-to-maturity securities and reported at amortized cost with related gains and losses reflected in earnings. Marketable securities in the form of debt securities are classified as available-for-sale securities and reported at their fair value, with unrealized gains and losses excluded from net income and reported as a separate component of shareholders’ equity (net of related tax effect) until realized. Any fluctuation in fair value related to investments that are deemed temporary, including any recoveries of previous write-downs, are recorded to accumulated other comprehensive income. Realized gains or losses are determined on the specific identification cost method and recorded as a charge to earnings, when realized.
	As of December 31, 2013 and January 1, 2013, our investments in marketable securities were classified in the held-to-maturity or available-for-sale categories.
Concentration of Credit Risk	'
	Concentration of Credit Risk
	Financial instruments which potentially subject us to a concentration of credit risk principally consist of cash and cash equivalents, investments and marketable securities. We currently maintain our day-to-day operating cash balances with a major financial institution. At times, our operating cash balances may be in excess of the FDIC insurance limit. At December 31, 2013, we had approximately $9.8 million of investments in marketable securities, of which $0.1 million were considered cash and cash equivalents, held by institutional brokers. We have placed a majority of our temporary excess cash with major financial institutions and institutional brokers that, in turn, invests in instruments with expected minimal volatility, such as money market funds, U.S. Treasury and direct agency obligations, municipal and bank securities and investment-grade corporate debt securities. Our investment policy limits the amount of exposure to any one institution or investment. We did not experience any losses in these accounts during fiscal 2013, 2012 or 2011, and believe we are not exposed to significant risk on cash and cash equivalents.
Inventories	'
	Inventories
	Inventories are comprised primarily of food and beverage products and are stated at the lower of cost (first-in, first-out) or market.
Property and Equipment	'
	Property and Equipment
	Property and equipment are recorded at cost and depreciated over their estimated useful lives. Leasehold improvements are amortized over the estimated useful life of the asset or the primary lease term of the respective lease including exercised options, whichever is shorter. Renewals and betterments that materially extend the life of an asset are capitalized while maintenance and repair costs are expensed as incurred. When property and equipment are sold or otherwise disposed of, the asset account and related accumulated depreciation or amortization accounts are relieved, and any gain or loss is included in earnings.
Goodwill and Intangible Assets	'
	Goodwill and Intangible Assets
	We perform impairment testing annually, during the fourth quarter, and more frequently if factors and circumstances indicate an impairment may have occurred. When evaluating goodwill for impairment, we first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, we calculate the implied estimated fair value of the reporting unit and compare it to the carrying value of the goodwill. If the carrying value of the goodwill is greater than the implied estimated fair value, an impairment charge is recorded to reduce the carrying value to the implied estimated fair value. This adjusted carrying value becomes the new goodwill accounting basis value.
	Definite-lived intangible assets are amortized over their estimated useful lives and tested for impairment when facts and circumstances indicate that the carrying values may not be recoverable. Trademarks with indefinite lives are amortized over 10 years and tested for impairment when facts and circumstances indicate that the carrying values may not be recoverable. We believe that no impairments of goodwill and intangible occurred during fiscal 2013, 2012, or 2011.
Long-Lived Assets	'
	Long-Lived Assets
	We assess potential impairments of our long-lived assets whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. The assets are generally reviewed for impairment in total as well as on a restaurant by restaurant basis. Factors considered include, but are not limited to, significant underperformance by the restaurant relative to expected historical or projected future operating results, significant changes in the manner of use of the acquired assets or the strategy for the overall business, and significant negative industry or economic trends. The recoverability is assessed in most cases by comparing the carrying value of the asset to the undiscounted cash flows expected to be generated by the asset. This assessment process requires the use of estimates and assumptions regarding future restaurant cash flows and estimated useful lives, which are subject to a significant degree of judgment. If these assumptions change in the future, we may be required to record impairment charges for these assets or for the entire restaurant. If the carrying amount is greater than the anticipated undiscounted cash flows, an impairment charge is recorded as the difference between the carrying amount and the assets fair value. In fiscal 2013, we recorded impairment expense of $3.1 million, which is included in “Loss on disposal of assets and impairments” in the Consolidated Statement of Income, representing a reduction in the carrying value of one of our underperforming BJ’s Restaurant & Brewhouse® restaurants. There was no long-lived asset impairment recorded during fiscal year 2012 or 2011.
Revenue Recognition	'
	Revenue Recognition
	Revenues from food and beverage sales at restaurants are recognized when payment is tendered at the point-of-sale. Revenues from the sale of gift cards are deferred and recognized upon redemption. Deferred gift card revenue, included in “Accrued expenses” on the accompanying Consolidated Balance Sheets, was $7.8 million and $7.2 million as of December 31, 2013 and January 1, 2013, respectively. We recognize gift card breakage income when the likelihood of the redemption of the cards becomes remote, which is typically 24 months after original issuance. Gift card breakage income is recorded in “Other income, net” on the Consolidated Statements of Income.
Customer Loyalty Program	'
	Customer Loyalty Program
	In July 2012, we introduced “BJ’s Premier Rewards” customer loyalty program to all of our restaurants. This program enables participants to earn points for each qualifying purchase. The points can then be redeemed for rewards including food discounts, trips, events and other items. We measure our total rewards obligation based on the estimated number of customers that will ultimately earn and claim rewards under the program, and record the estimated related expense as reward points accumulate. These expenses are accrued for and recorded as marketing expenses and are included in “Occupancy and operating” expenses on our Consolidated Statements of Income.
Sales Taxes	'
	Sales Taxes
	Revenues are presented net of sales taxes. The obligation is included in other accrued expenses until the taxes are remitted to the appropriate taxing authorities.
Advertising Costs	'
	Advertising Costs
	Advertising costs are expensed as incurred. Advertising expense for fiscal 2013, 2012, and 2011 was approximately $17.1 million, $10.6 million, and $7.2 million, respectively.
Income Taxes	'
	Income Taxes
	We provide for income taxes based on our estimate of federal and state tax liabilities. Our estimates include, but are not limited to, effective state and local income tax rates, allowable tax credits for items such as FICA taxes paid on reported tip income and estimates related to depreciation expense allowable for tax purposes. We usually file our income tax returns several months after our fiscal year-end. We file our tax returns with the advice and compilation of tax consultants. All tax returns are subject to audit by federal and state governments, usually years after the returns are filed, and could be subject to differing interpretation of the tax laws.
	We utilize the liability method of accounting for income taxes. Deferred income taxes are recognized based on the tax consequences in future years of differences between the tax basis of assets and liabilities and their financial reporting amounts at each year-end based on enacted tax laws and statutory tax rates applicable to the periods in which differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. The provision for income taxes represents the tax payable for the period and the change during the period in deferred tax assets and liabilities.
	We recognize the impact of a tax position in our financial statements if that position is more likely than not of being sustained on audit, based on the technical merits of the position. Interest and penalties related to uncertain tax positions are included in income tax expense.
Restaurant Opening Expense	'
	Restaurant Opening Expense
	Restaurant payroll, supplies, training, other start-up costs and rent expense incurred prior to the opening of a new restaurant are expensed as incurred.
Legal and Other Settlements	'
	Legal and Other Settlements
	Legal settlements primarily relate to the proposed settlements of certain California employment practices lawsuits and alleged trademark infringements. We agreed to these settlements, which are subject to court approval, in order to avoid the costs, risks and uncertainties inherent in litigation and to eliminate the further diversion of our management’s time and attention, and without admitting any liability on our part. Other settlements relate to an employment separation, a Texas Alcoholic Beverage Commission settlement related to our beer model, and a California sales tax audit assessment.
Investment Settlement	'
	Investment Settlement
	In December 2009, we agreed to a settlement with our former broker-dealer for the full liquidation of our auction rate securities (“ARS”) investment portfolio. Under the terms of the settlement agreement, we were entitled to potential future recoveries of our loss on that portfolio based on the performance of those auction rate securities through December 2012. We received recoveries of approximately $0.8 million and $0.6 million for fiscal 2012 and 2011, respectively.
Leases	'
	Leases
	We lease the majority of our restaurant locations. We account for our leases in accordance with U.S. GAAP, which require that our leases be evaluated and classified as operating or capital leases for financial reporting purposes. The term used for this evaluation includes renewal option periods only in instances in which the exercise of the renewal option can be reasonably assured and failure to exercise such option would result in an economic penalty. All of our restaurant leases are classified as operating leases. We disburse cash for leasehold improvements, furniture and fixtures and equipment to build out and equip our leased premises. Tenant improvement allowance incentives may be available to partially offset the cost of developing and opening the related restaurants, pursuant to agreed-upon terms in our leases. Tenant improvement allowances can take the form of cash payments upon the opening of the related restaurants, full or partial credits against minimum or percentage rents otherwise payable by us or a combination thereof. All tenant improvement allowances received by us are recorded as a deferred lease incentive and amortized over the term of the lease. The related cash received from the landlord is reflected as “Landlord contribution for tenant improvements, net” within operating activities of our Consolidated Statements of Cash Flows.
	The lease term used for straight-line rent expense is calculated from the date we obtain possession of the leased premises through the lease termination date. We expense rent from possession date through restaurant open date as preopening expense. Once a restaurant opens for business, we record straight-line rent over the lease term plus contingent rent to the extent it exceeded the minimum rent obligation per the lease agreement.
	There is potential for variability in the rent holiday period, which begins on the possession date and ends on the restaurant open date, during which no cash rent payments are typically due under the terms of the lease. Factors that may affect the length of the rent holiday period generally relate to construction related delays. Extension of the rent holiday period due to delays in restaurant opening will result in greater preopening rent expense recognized during the rent holiday period and lesser occupancy expense during the rest of the lease term (post-opening).
	For leases that contain rent escalations in which the amount of future rent is certain or can be reasonably calculated, we record the total rent payable during the lease term, as determined above, on the straight-line basis over the term of the lease (including the rent holiday period beginning upon our possession of the premises), and record the difference between the minimum rents paid and the straight-line rent as deferred rent. Certain leases contain provisions that require additional rent payments based upon restaurant sales volume (“contingent rent”). Contingent rent is accrued each period as the liabilities are incurred, in addition to the straight-line rent expense noted above. This results in some variability in occupancy expense as a percentage of revenues over the term of the lease in restaurants where we pay contingent rent.
	Management makes judgments regarding the probable term for each restaurant property lease, which can impact the classification and accounting for a lease as capital or operating, the rent holiday and/or escalations in payments that are taken into consideration when calculating straight-line rent and the term over which leasehold improvements for each restaurant are amortized. These judgments may produce materially different amounts of depreciation, amortization and rent expense than would be reported if different assumed lease terms were used.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	The carrying value of cash and cash equivalents, investments classified as held-to-maturity or available-for-sale or other current assets, accounts receivable and current liabilities approximate fair values due to the short-term maturity of these instruments. Investments classified as non-current assets are recorded at fair value based on valuation models and methodologies provided by a third party using either “Level 2” or “Level 3” inputs when the fair value of the investment cannot be determined based on current trades on the open market. Temporary changes in fair value of available-for-sale securities results in unrealized holding gains and losses being recorded in the “Other comprehensive income” component of shareholders’ equity and does not affect net income for the applicable accounting period. Declines in fair value below our carrying value deemed to be other than temporary are charged against net earnings.
Net Income Per Share	'
	Net Income Per Share
	Basic net income per share is computed by dividing the net income attributable to common shareholders by the weighted average number of common shares outstanding during the period. Diluted net income per share reflects the potential dilution that could occur if stock options issued by us to sell common stock at set prices were exercised and if restrictions on restricted stock units issued by us were to lapse (collectively, equity awards). The consolidated financial statements present basic and diluted net income per share. Common stock equivalents included in the diluted computation represent shares to be issued upon assumed exercises of outstanding stock options and the assumed lapsing of the restrictions on restricted stock units using the treasury stock method.
Stock-Based Compensation	'
	Stock-Based Compensation
	Under shareholder approved stock-based compensation plans, we have granted incentive stock options, non-qualified stock options and restricted stock units that generally vest over five years and expire ten years from the date of grant. Stock-based compensation is measured in accordance with U.S. GAAP based on the underlying fair value of the awards granted. In valuing stock options, we are required to make certain assumptions and judgments regarding the grant date fair value utilizing the Black-Scholes option-pricing model. These judgments include expected volatility, risk free interest rate, expected option life, dividend yield and vesting percentage. These estimations and judgments are determined by us using many different variables that, in many cases, are outside of our control. The changes in these variables or trends, including stock price volatility and risk free interest rate, may significantly impact the grant date fair value resulting in a significant impact to our financial results. The cash flow tax benefits resulting from tax deductions in excess of the compensation cost recognized for those options (excess tax benefits) are required to be classified as financing cash flows.
Marketable Securities	'
	Marketable securities, which we have the intent and ability to hold until maturity, are classified as held-to-maturity securities and reported at amortized cost, which approximates fair value. Marketable securities, in the form of municipal variable rate demand notes with expected put dates prior to the contractual maturity of the underlying debt security and backed by financial institutions in the form of a letter of credit or liquidity facility, are classified as available-for-sale securities. These securities are reported at fair value, using a market approach and classified as Level 2 fair value measurements, as further described in Note 3. Any unrealized gains or losses on available-for-sale securities would be recorded in other comprehensive income. As of December 31, 2013 and January 1, 2013, there were no unrealized gains or losses with respect to available-for-sale securities.
	We determine the appropriate classification of our marketable securities at the time of purchase and reevaluate the held-to-maturity or available-for-sale designations as of each balance sheet date. Marketable securities are classified as either short-term or long-term based on each instrument’s underlying contractual maturity date or the expected put date. Marketable securities with maturities or expected put dates of 12 months or less are classified as short-term and marketable securities with maturities or expected put dates greater than 12 months are classified as long-term. Gains or losses are determined on the specific identification cost method and recorded in earnings when realized.
Fair Value Measurement	'
	In accordance with U.S. GAAP, a framework for using fair value to measure assets and liabilities was established by defining a three-tier fair value hierarchy, which prioritizes the inputs used to measure fair value. These tiers include:
		•	Level 1: Defined as observable inputs such as quoted prices in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.
		•	Level 2: Defined as pricing inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors, and current market and contractual prices for the underlying instruments, as well as other relevant economic measures.
		•	Level 3: Defined as pricing inputs that are generally less observable from objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value.
