Where is the fast food chain "Panda Express" headquartered?

The fast-food chain Panda Express is headquartered in Rosemead, California. The exact reason for choosing this location is not explicitly stated, but there are a few possible factors. One likely reason is the historical connection, as Panda Express was founded in 1983 by Andrew Cherng and Peggy Cherng in Pasadena, which is a neighboring city to Rosemead. Being situated in close proximity to the original location allows for better management and accessibility. Additionally, the choice of Rosemead could be attributed to its central location within California, making it easier to oversee multiple restaurant locations across the state.
