In 1973, when Andrew's parents moved to the United States, Andrew went into Business with his Father and opened their first Panda Inn restaurant in Pasadena, California. At the beginning, Business was lacking to the degree that Andrew had to offer special deals and freebies so that customers would dine at Panda Inn. In 1982, Peggy joined Andrew in the restaurant Business. While operating Panda Inn, Andrew became acquainted with then-UCLA head football coach Terry Donahue, as well as Terry's brother Dan, who happened to be in the real estate Business. It was because of this connection that in 1983, Donahue Schriber Real Estate, the manager of the Glendale Galleria, invited the Cherngs to develop a fast-food version of Panda Inn for the Galleria's food court, and Panda Express was launched that October. A second location was opened two years later at the Westside Pavilion in 1985. The chain has steadily expanded across the United States since then. Chef Andy Kao claims to have developed the original Chinese-American orange chicken recipe at a Panda Express in Hawaii in 1987.
