Orange Chicken is pretty much what I think of when I think of Panda Express, and is made of chunks of battered and deep-fried chicken tossed in a wok with a tangy, sweet, mildly-spicy sauce.
Panda Express restaurants typically close at around 9pm. Under summer hours, they stay open an hour or two later; the Panda Express restaurants in my area close at either 10:30pm or 11:00pm this summer.
