Debt Disclosure [Abstract]
Long-Term Debt	Long-Term Debt As of March 26, 2014, Denny's Corporation and certain of its subsidiaries had a credit facility comprised of a senior secured term loan in an original principal amount of $60 million and a $190 million senior secured revolver (with a $30 million letter of credit sublimit). As of March 26, 2014, we had outstanding term loan borrowings under the credit facility of $57.0 million and outstanding letters of credit under the senior secured revolver of $24.6 million. There were $98.3 million of revolving loans outstanding at March 26, 2014. These balances resulted in availability of $67.1 million under the revolving facility. The weighted-average interest rate under the term loan and on outstanding revolver loans was 2.16% and 2.17% as of March 26, 2014 and December 25, 2013, respectively. A commitment fee of 0.35% is paid on the unused portion of the revolving credit facility. Borrowings under the credit facility bear a tiered interest rate based on the Company's consolidated leverage ratio and was initially set at LIBOR plus 200 basis points. The credit facility includes an accordion feature that would allow us to increase the size of the facility to $300 million. The maturity date for the credit facility is April 24, 2018. The credit facility is guaranteed by the Company and its material subsidiaries and is secured by substantially all of the assets of the Company and its subsidiaries, including the stock of the Company's subsidiaries. It includes negative covenants that are usual for facilities and transactions of this type. The credit facility also includes certain financial covenants with respect to a maximum consolidated leverage ratio, a minimum consolidated fixed charge coverage ratio and maximum capital expenditures. The term loan under the credit facility requires amortization of the original term loan balance of 5% per year in the first two years, 7.5% in the subsequent two years and 10% in the fifth year with the balance due at maturity. We will be required to make certain mandatory prepayments under certain circumstances and will have the option to make certain prepayments under the credit facility. The credit facility includes events of default (and related remedies, including acceleration and increased interest rates following an event of default) that are usual for facilities and transactions of this type. During the quarter ended March 26, 2014, we paid $0.8 million on the term loan under the credit facility. Interest Rate Hedges We have entered into interest rate hedges that cap the LIBOR rate on borrowings under our credit facility. The 200 basis point LIBOR cap applies to $125 million of borrowings from April 14, 2013 through April 13, 2014 and to $150 million of borrowings from April 14, 2014 through March 31, 2015. We also have entered into interest rate swaps to hedge a portion of the cash flows of our floating rate debt from March 31, 2015 through March 29, 2018. We designated the interest rate swaps as cash flow hedges of our exposure to variability in future cash flows attributable to payments of LIBOR due on a related $150 million notional debt obligation from March 31, 2015 through March 31, 2017 and a related $140 million notional debt obligation from April 1, 2017 through March 29, 2018. Under the terms of the swaps, we will pay an average fixed rate of 3.12% on the notional amounts and receive payments from a counterparty based on the 30-day LIBOR rate. As of March 26, 2014, the fair value of the interest rate swaps was $2.5 million, which is recorded as a component of other noncurrent assets on our Condensed Consolidated Balance Sheets. See Note 13 for the amounts recorded in accumulated other comprehensive loss related to the interest rate swaps. We believe that our estimated cash flows from operations for 2014, combined with our capacity for additional borrowings under our credit facility, will enable us to meet our anticipated cash requirements and fund capital expenditures over the next twelve months.
