Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	1. Description of Business Kona Grill, Inc., including its wholly-owned subsidiaries, (referred to herein as the “Company” or “we,” “us,” and “our”) owns and operates upscale casual dining restaurants under the name “Kona Grill.” Our restaurants feature a diverse selection of contemporary American favorites and award-winning sushi items that are prepared fresh daily at each restaurant location. As of December 31, 2016, 45 23 one Basis of Presentation The consolidated financial statements include the accounts and operations of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Reclassifications Certain reclassifications of prior year’s financial statement amounts have been made to conform to the current year presentation including: ● As of January 1, 2016 $1,865,000 December 31, 2015, ● As of January 1, 2016, $113,000 $82,000 December 31, 2016 December 31, 2015, Recently Issued Accounting Standards." Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Cash and Cash Equivalents We consider all highly liquid investments that are readily convertible into cash and have an original maturity of three Amounts receivable from credit card processors are also considered cash equivalents because they are both short-term and highly liquid in nature and are typically converted to cash within several business days of the sales transaction. Investments Investments consist primarily of certificates of deposit that are generally highly liquid in nature. We classify our investments based on the intended holding period. Inventory Inventory consists of food and beverage products that are valued at the lower of cost or market using the first first Concentration of Credit Risk Financial instruments that potentially subject us to a concentration of credit risk principally consist of cash and cash equivalents, investments and accounts receivable. Concentration of credit risk is limited by diversifying cash deposits among a variety of high credit-quality issuers. At times, cash and cash equivalent balances may Property and Equipment Property and equipment are recorded at cost. We capitalize all direct costs on the construction of leasehold improvements and interest incurred during the construction and development period. Leasehold improvements are amortized over the shorter of the useful life of the asset or the related lease term that includes reasonably assured lease renewals as determined on the date of acquisition of the leasehold improvement. Improvements that materially extend the life of an asset are capitalized while repair and maintenance costs are expensed as incurred. Depreciation and amortization are recorded on a straight-line basis over the following estimated useful lives: Furniture and fixtures (in years) 5 - 7 Equipment (in years) 2 - 7 Computer software and electronic equipment (in years) 3 Leasehold improvements Shorter of the useful life or the lease term Impairment of Long-Lived Assets We evaluate long-lived assets, such as property and equipment, for impairment whenever events or changes in restaurant operating results indicate that the carrying value of those assets may As a result of the process described above, we recorded long-lived asset impairment charge of $12.5 December 31, 2016. 2). Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, a three Level 1: Fair values determined by quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access. Level 2: Fair values utilize inputs other than quoted prices that are observable for the asset or liability, and may Level 3: Fair values determined by unobservable inputs that are not corroborated by market data and may The carrying value for certain of our financial instruments, including cash and cash equivalents, accounts receivable and accounts payable approximates fair value because of their short-term nature. Our investments represent certificates of deposit and are considered available-for-sale securities that are valued using market observable inputs (Level 2). 2 In addition to our assets and liabilities that are measured at fair value on a recurring basis, we are required by GAAP to measure certain assets and liabilities at fair value on a nonrecurring basis after initial recognition. Generally, assets, liabilities and reporting units are measured at fair value on a nonrecurring basis as a result of impairment reviews and any resulting impairment charge. In connection with our impairment review of long-lived assets described in Note 2, 3 3 Leases We lease our restaurant locations under operating lease agreements with initial terms of approximately 10 20 tenant tenant Revenue Recognition Revenues from food, beverage, and alcohol sales are recognized when payment is tendered In February April 2016, six six not December 31, 2016. Sales Taxes Revenues are presented net of sales taxes. The sales tax obligation is included in accrued expenses until the taxes are remitted to the appropriate taxing authorities. Advertising and Marketing Costs Advertising and marketing costs are expensed as incurred. Advertising and marketing expense for 2016, 2015 2014 $935,000, $744,000 $461,000, Preopening Expense Costs directly related to the opening of new restaurants, including employee relocation, travel, employee payroll and related training costs, and rent expense subsequent to the date we take possession of the property through the restaurant opening are expensed as incurred. Stock-Based Compensation We maintain stock award plans under which we may five 25% four 25% one may Income Taxes We utilize the liability method of accounting for income taxes. Under the liability method, deferred tax assets and liabilities are computed at each balance sheet date for temporary differences between the consolidated financial statements and tax basis of assets and liabilities that will result in taxable or deductible amounts in the future based on tax rates in effect in the years in which the temporary differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts that will more likely than not be realized. We recognize the impact of a tax position in our financial statements if that position more likely than not will be sustained upon examination by a tax authority. We recognize accrued interest and penalties related to uncertain tax positions as income tax expense. Net Income (Loss) Per Share Basic income (loss) per common share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted income (loss) per share is computed similarly except that weighted average common shares is increased to reflect all dilutive instruments, including stock options. The dilutive effects of the dilutive securities are calculated using the treasury stock method and only those instruments that result in a reduction in income per share are included in the calculation.

We account for stock-based compensation using the fair value recognition provisions. Compensation expense is recognized ratably over the vesting term of the option and is included in general and administrative expenses. The following table presents information related to stock-based compensation (in thousands): Year Ended December 31, 201 6 201 5 201 4 Stock-based compensation $ 1,262 $ 1,363 $ 856 The fair value of each option award is estimated on the date of grant using the Black-Scholes option pricing model and is affected by assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, the actual and projected employee stock option exercise behavior, expected volatility, risk-free interest rate, expected dividends, and expected term. Expected volatility is based on the historical volatility of our stock. The expected term of the options represents the estimated period of time until exercise and is based on historical experience of similar awards, giving consideration to the contractual terms, vesting schedules and expectations of future employee behavior. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the option. We have not paid dividends in the past and do not plan to pay any dividends in the near future. Compensation expense is recognized only for those options expected to vest, with forfeitures estimated based on our historical experience and future expectations. The fair value of stock options granted was estimated at the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions: 201 6 201 5 201 4 Expected volatility 45.2 % 40.7 % 36.8 % Risk-free interest rate 0.9 % 0.9 % 0.7 % Dividend yield 0.0 % 0.0 % 0.0 % Expected life (in years) 3.2 3.0 2.9 Weighted average fair value per option granted $ 4.57 $ 6.67 $ 4.15 Activities under our stock award plans during 2016, 2015 2014 Shares Under Option Weighted Average Exercise Price Weighted Average Remaining Contractual Term (years) Aggregate Intrinsic Value (in thousands) Outstanding options at December 31, 2013 783,297 $ 6.94 Granted 309,900 16.24 Forfeited (26,650 ) 13.08 Exercised (326,297 ) 6.82 Outstanding options at December 31, 2014 740,250 10.66 Granted 380,268 23.28 Forfeited (81,213 ) 19.73 Exercised (77,837 ) 7.40 Outstanding options at December 31, 2015 961,468 15.15 Granted 251,532 14.26 Forfeited (111,094 ) 11.49 Exercised (127,706 ) 6.73 Outstanding options at December 31, 2016 974,200 $ 16.44 2.7 $ 841,000 Exercisable at December 31, 2016 475,742 $ 15.46 2.2 $ 690,000 The intrinsic value of options exercised during 2016, 2015 2014 $800,000, $1.2 $5.0 2016, 2015 2014 $1.1 $1.0 $0.7 December 31, 2016, $1.8 2.2 Information regarding options outstanding and exercisable at December 31, 2016 Options Outstanding Options Exercisable Range of Exercise Prices Shares Weighted Average Remaining Contractual Life (years) Weighted Average Exercise Price Shares Weighted Average Exercise Price $4.99 – $8.71 180,900 0.9 $ 7.94 142,400 $ 7.71 $11.82 – $18.85 489,582 3.2 $ 15.21 199,475 $ 15.59 $23.49 303,718 3.1 $ 23.49 133,867 $ 23.49 974,200 2.7 $ 16.44 475,742 $ 15.46

Actual results could differ from those estimates.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents We consider all highly liquid investments that are readily convertible into cash and have an original maturity of three Amounts receivable from credit card processors are also considered cash equivalents because they are both short-term and highly liquid in nature and are typically converted to cash within several business days of the sales transaction.

Concentration of credit risk is limited by diversifying cash deposits among a variety of high credit-quality issuers. At times, cash and cash equivalent balances may
Property, Plant and Equipment, Policy [Policy Text Block]	Property and Equipment Property and equipment are recorded at cost. We capitalize all direct costs on the construction of leasehold improvements and interest incurred during the construction and development period. Leasehold improvements are amortized over the shorter of the useful life of the asset or the related lease term that includes reasonably assured lease renewals as determined on the date of acquisition of the leasehold improvement. Improvements that materially extend the life of an asset are capitalized while repair and maintenance costs are expensed as incurred. Depreciation and amortization are recorded on a straight-line basis over the following estimated useful lives: Furniture and fixtures (in years) 5 - 7 Equipment (in years) 2 - 7 Computer software and electronic equipment (in years) 3 Leasehold improvements Shorter of the useful life or the lease term
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment of Long-Lived Assets We evaluate long-lived assets, such as property and equipment, for impairment whenever events or changes in restaurant operating results indicate that the carrying value of those assets may As a result of the process described above, we recorded long-lived asset impairment charge of $12.5 December 31, 2016. 2).
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, a three Level 1: Fair values determined by quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access. Level 2: Fair values utilize inputs other than quoted prices that are observable for the asset or liability, and may Level 3: Fair values determined by unobservable inputs that are not corroborated by market data and may The carrying value for certain of our financial instruments, including cash and cash equivalents, accounts receivable and accounts payable approximates fair value because of their short-term nature. Our investments represent certificates of deposit and are considered available-for-sale securities that are valued using market observable inputs (Level 2). 2 In addition to our assets and liabilities that are measured at fair value on a recurring basis, we are required by GAAP to measure certain assets and liabilities at fair value on a nonrecurring basis after initial recognition. Generally, assets, liabilities and reporting units are measured at fair value on a nonrecurring basis as a result of impairment reviews and any resulting impairment charge. In connection with our impairment review of long-lived assets described in Note 2, 3 3
Lease, Policy [Policy Text Block]	Leases We lease our restaurant locations under operating lease agreements with initial terms of approximately 10 20 tenant tenant

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Compensation We maintain stock award plans under which we may five 25% four 25% one may
Income Tax, Policy [Policy Text Block]	Income Taxes We utilize the liability method of accounting for income taxes. Under the liability method, deferred tax assets and liabilities are computed at each balance sheet date for temporary differences between the consolidated financial statements and tax basis of assets and liabilities that will result in taxable or deductible amounts in the future based on tax rates in effect in the years in which the temporary differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts that will more likely than not be realized. We recognize the impact of a tax position in our financial statements if that position more likely than not will be sustained upon examination by a tax authority. We recognize accrued interest and penalties related to uncertain tax positions as income tax expense.
Earnings Per Share, Policy [Policy Text Block]	Net Income (Loss) Per Share Basic income (loss) per common share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted income (loss) per share is computed similarly except that weighted average common shares is increased to reflect all dilutive instruments, including stock options. The dilutive effects of the dilutive securities are calculated using the treasury stock method and only those instruments that result in a reduction in income per share are included in the calculation.
