Bon Appétit spends a day on the line with Executive Chef Aiguo Yang at Panda Inn, the legendary California restaurant chain that inspired Panda Express. Founded 50 years ago in Pasadena by Andrew and Peggy Cherng and Master Chef Ming-Tsai Cherng, Panda Inn helped define Chinese-American cuisine with iconic dishes like Orange Chicken and Panda Beef. Today, Chef Yang continues that legacy across the restaurant’s four California locations, blending tradition, technique, and the flavors that sparked a nationwide dining phenomenon.
