PF chang does not serve real Chinese food, they serve American Chinese food. It is different thing. Typically American Chinese food does not require a lot of skill to do it. Unlike authentic Chinese cuisine which requires a lot of skill and time to cook.
The problem is PF chang does not even know how to cook a simple dish. I have had the worst roast duck in PF Chang, house special pork rib was aweful. I don't understand how they can screw up such simple dish. My wife and I can make better dish than them. Price is way too expensive. I can easily find a bundle of Chinese restaurant better than PF Chang around Phoenix area. Sigh
