Many people do not know that Pei Wei is PF Chang's little brother. The food at both resturants is similar, although Pei Wei requires standing in line and paying before you get your food.
You do, however, get to see the food getting made (something back there flares up every 5 minutes or so. Very cool) and you get great service. They'll bring your food out to you. Well, I guess that's as far as it goes with the service.
The food is great. I've never had anything I didn't like, although a few of the dishes have little green things that are incredibly spicy. Weirdly spicy.
Also, make sure you get some napkins. They have awesome napkins. Almost like cloth. I love those napkins.
