PF Chang's Lite.
Pei Wei reminds me of picking a Chinese restaurant for takeout. Is there really that much of a difference? It doesn't really matter which restaurant you pick...the dishes are going to taste about the same from restaurant ot restaurant. Pei Wei has good tasting food...but there isn't anything distinct or mind-blowing about their offerings. I wouldn't say you shouldn't go here and I wouldn't say you should. It's good food, not great food...so my mom won't be hearing about it any time soon.
Try: The Pad Thai (pretty tasty)
Avoid: The large portions unless you're really hungry
