Business And Basis Of Presentation [Abstract]
Business And Basis of Presentation	(1) Organization and Basis of Presentation Background Del Frisco’s Restaurant Group, Inc. (the Company) is incorporated in Delaware as a corporation. Prior to its initial public offering (IPO) in 2012, the Company was a wholly owned subsidiary of LSF5 Wagon Holdings, LLC (Wagon), which is a wholly owned subsidiary of LSF5 COI Holdings, LLC (Holdings), which is majority owned by Lone Star Fund V (U.S.), L.P. (the Fund), which is a private investment fund. Effective December 13, 2006, the Fund, through Holdings, acquired all of the outstanding capital stock of Lone Star Steakhouse & Saloon, Inc. (Star), through a series of transactions pursuant to an Agreement and Plan of Merger (the Acquisition). Prior to the Acquisition, Star was a public company that owned and operated steakhouse restaurants under four different restaurant brands, which included Lone Star Steakhouse & Saloon (Lone Star), Texas Land & Cattle Steak House (TXLC), Sullivan’s Steakhouse (Sullivan’s), and Del Frisco’s Double Eagle Steak House (Del Frisco’s). In connection with the Acquisition, Holdings contributed all of the assets, restaurant operations, trade names, and other intangible assets of its Lone Star and TXLC restaurants to LSF5 Cowboy Holdings, LLC (Casual Dining Companies), which is a wholly owned subsidiary of Holdings. In addition, LS Management, Inc. (LSM), which was previously a wholly owned subsidiary of Star that provided all of the accounting, legal, and other administrative support to all of Star’s restaurants, was contributed to the Casual Dining Companies. Concurrently, the remaining assets and restaurant operations of Star, which primarily included the Del Frisco’s and Sullivan’s restaurants as well as LS Finance, LLC which was previously a wholly owned subsidiary of Star that provided all of the cash management and treasury support to all of Star’s restaurants, were contributed to the Company. On July 26, 2012, the Company priced a $75,400 IPO of 5.8 million shares of common stock at $13.00 per share. On July 27, 2012, the Company’s common stock began trading on the NASDAQ Global Select Market under the ticker symbol “DFRG.” Upon the August 1, 2012 closing of the IPO, the Company received net proceeds of $70,122, reflecting $5,278 of underwriting discounts and commissions. Additionally, the Company incurred $3,666 in offering costs that reduced the net proceeds available to additional paid in capital. At the completion of the IPO, Wagon owned approximately 18.0 million shares of common stock, or approximately 75.6% of the Company’s outstanding shares. Prior to the IPO closing, the Company converted from a limited liability company to a corporation and in connection therewith, the Company’s then-outstanding membership interests were converted into approximately 18.0 million shares of Company common stock (the “Conversion”). As part of the IPO, the Company established its authorized shares at 10,000,000 shares of preferred stock, $0.001 par value per share, and 190,000,000 shares of common stock, $0.001 par value per share. At August 1, 2012, the closing date of the IPO, the Company had a total of approximately 23.8 million common shares issued and outstanding. The Company used a portion of the net proceeds from the IPO to repay $61,000 of amounts outstanding under its credit facility on August 1, 2012. In addition, the Company used $3,000 of the net proceeds to make a one-time payment to an affiliate of the Fund in consideration for the termination of an asset advisory agreement upon consummation of the IPO, which is reflected as an operating expense in the consolidated statements of income and comprehensive income. The remainder of the net proceeds were used for working capital and other general corporate purposes. In conjunction with the repayment of amounts outstanding under the credit facility, the Company wrote-off $1,649 in unamortized debt issuance costs in the third quarter of fiscal 2012. On March 7, 2013, a secondary public offering of the Company’s common stock was completed by the Fund. The selling shareholder sold 4,750,000 previously outstanding shares. In addition, on April 10, 2013, the shareholder sold an additional 150,000 shares of common stock to cover over-allotments related to the March 7, 2013 offering. The Company did not receive any proceeds from the offering. The selling shareholder paid all of the underwriting discounts and commissions associated with the sale of the shares; however, the Company incurred $412 in costs and registration expenses related to this offering.
