Comparable Restaurant Sales Increase 6.9%; Earnings Guidance Increases to $0.15-$0.17 per Diluted Share

LOS ANGELES–(BUSINESS WIRE)–California Pizza Kitchen, Inc. (Nasdaq: CPKI) announced today that revenues increased 16.4% to $146.0 million for the fourth quarter ended December 31, 2006 versus $125.4 million in the fourth quarter of 2005. Comparable restaurant sales increased approximately 6.9% compared to 5.3% in the fourth quarter a year ago.

During its November 9, 2006 conference call, the Company forecasted a fourth quarter comparable restaurant sales increase of approximately 5.0%-6.0% and earnings per diluted share in the range of $0.13-$0.15 including the effects of stock-based compensation expense and the impact of the October 6, 2005 lease accounting pronouncement. Based on fourth quarter 2006 revenues and comparable restaurant sales results, management is increasing its earnings per diluted share guidance to $0.15-$0.17. This revised guidance range represents either a marginal decrease or no change to earnings per share over the fourth quarter of 2005 primarily due to pre-opening costs for 11 restaurants opened during the fourth quarter of 2006 compared to four restaurants opened during the fourth quarter of 2005.

In the fourth quarter of 2006, the Company added nine full service restaurants and two CPK/ASAP restaurants. Full service restaurant openings included Foxwoods Resort Casino in Mashantucket, Connecticut; Boulder, Colorado; Hunt Valley, Maryland; Glendale, Wisconsin; Vista, California; Chula Vista, California; Estero, Florida; West Covina, California; and Honolulu, Hawaii. CPK/ASAP new openings included Elmhurst, New York and Sherman Oaks, California.

The Company intends to release its fourth quarter earnings on February 15, 2007 at approximately 4:00 pm EST with a conference call to follow on the same day at approximately 5:00 pm EST. A webcast of the conference call can be accessed at www.cpk.com.
