Peter Piper Pizza is planning a five-year expansion in the Dallas/Fort Worth area. The pizza and entertainment chain plans to open 10 new prototype restaurants and create approximately 350 new jobs. The site search is underway for the first four locations, slated to open for business by year-end 2008. The chain's Dallas brokers, Jason Puig and Lynn Dowdle of The Staubach Co., are looking into several areas of interest including Frisco, McKinney, Arlington, Grapevine and Hurst.
