Debt Disclosure [Abstract]
Credit Agreement	Senior Credit Facility: During the period of February 2008 through October 23, 2011, we were party to a senior credit facility (the “Credit Agreement”), which provided for borrowings up to $350 million (with sublimits of $75 million and $20 million for letters of credit and swingline loans, respectively) with proceeds available to be used for working capital, capital expenditures, dividends, share repurchases and other matters. The Credit Agreement had an Increase Option for $150 million (subject to additional lender group commitments). The Credit Agreement was unsecured and would have matured in February 2012. On October 24, 2011, we entered into a new Senior Credit Facility with essentially the same lender group as under the previous Credit Agreement. The new Senior Credit Facility provides for borrowings of up to $250 million (with sublimits of $250 million and $20 million for letters of credit and swingline loans, respectively). This agreement is unsecured and matures in October 2016, with proceeds available to be used for working capital, capital expenditures, dividends, share repurchases and other matters. At December 29, 2012 and December 31, 2011, there were no outstanding borrowings under the new Senior Credit Facility. There were $51.4 million and $15.0 million outstanding letters of credit as of December 29, 2012 and December 31, 2011, respectively. Borrowings bear interest at either the bank’s base rate (3.25% at December 29, 2012) or the London Inter-Bank Offer Rate (0.21% at December 29, 2012) plus an additional amount ranging from 0.40% to 1.00% per annum, adjusted quarterly based on our leverage ratio (0.50% at December 29, 2012). We are also required to pay, quarterly in arrears, a commitment fee ranging from 0.08% to 0.20% per annum and adjusted quarterly based on our leverage ratio, for unused capacity (0.10% at December 29, 2012). There are no compensating balance requirements associated with the Senior Credit Facility. The Senior Credit Facility requires quarterly compliance with respect to two material covenants: a fixed charge coverage ratio and a leverage ratio. The fixed charge coverage ratio compares earnings before interest, taxes, depreciation, amortization, stock compensation and rent expense (“consolidated EBITDAR”) to the sum of interest paid and rental expense (excluding any straight-line rent adjustments). The leverage ratio compares total debt plus rental expense (excluding any straight-line rent adjustments) multiplied by a factor of six to consolidated EBITDAR. The Senior Credit Facility also contains certain other restrictions regarding additional indebtedness, capital expenditures, business operations, guarantees, investments, mergers, consolidations and sales of assets, transactions with subsidiaries or affiliates, and liens. We were in compliance with all covenants at December 29, 2012.

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.
