Grill Concepts Reports Increased Comparable Sales for Fourth Quarter and Full Year

LOS ANGELES, Jan. 15, 2008 (PRIME NEWSWIRE) -- Grill Concepts, Inc.
(Nasdaq:GRIL), which operates The Grill on the Alley and Daily Grill-branded
restaurants, today reported preliminary same-store sales increases for its
fiscal fourth quarter and full year ended December 30, 2007.

Fiscal 2007 was a 52-week year, with 13 weeks in each quarter, while fiscal 2006
was a 53-week year, including an additional week in the fourth quarter.

Based on a 13-week comparison, consolidated preliminary same-store sales
increased 0.2 percent for the fourth quarter of fiscal 2007. Grill Concepts'
fiscal 2007 fourth quarter was a 13-week period which included the Christmas day
closure of nearly 80 percent of its company-owned restaurants. The comparable
13-week period of fiscal 2006 fourth quarter ended December 24, 2006 and,
therefore, does not reflect the impact of Christmas day closures. Based on a
12-week comparison, consolidated preliminary same-store sales increased 1.9
percent over the fourth quarter of fiscal 2006, with The Grill on the Alley and
Daily Grill restaurants posting comparable sales gains of 1.9 percent and 2.0
percent, respectively.

Based on a 52-week comparison, the company's consolidated preliminary same-store
sales increased 7.4 percent for fiscal 2007. The Grill on the Alley restaurants
recorded 11.7 percent gains in comparables sales for the fiscal year, and the
Daily Grill restaurants posted same-store sales increases of 4.7 percent.

As previously announced, Chief Executive Officer Philip Gay and Chief Financial
Officer Wayne Lipschitz will present a company overview at the ICR XChange
