Head Chef Andy Kao has completely changed the way Americans view Chinese food, in one of the most innovate franchises of the past decade. With more than 1,200 locations across the country and Puerto Rico, it is the fastest growing Chinese chain in the world. Perhaps its most famous dish, known to nearly anyone who has walks through the doors, is Panda's orange chicken. Many who order the two-entrée plate have two orders of the orange chicken. However, Panda Express comes up with new recipes all the time, and signs constantly line the front of the location advertising new dishes. Its famous sauces are also available for purchase.
