I enjoy the food at Pei Wei MORE than PF Chang's. I use all my PF Chang gift certificates here :)
The menu is smaller, the portions are a little smaller, so are the prices, but the food is sooooo much more flavorful in my opinion. They have vegetarian and gluten free options.
Pei Wei is "casual" dining - order at the counter, take a seat, they bring the food to you. Get your own drink refills but leave your table as is when you are done, they'll clear it. I usually leave a little tip :)
Our favorites:
Crab Wontons
Hot & Sour Soup
Honey Seared Shrimp
Pei Wei Spicy Chicken
Thai Dynamite Tofu or Vegetables
Never had a bad meal here, and never left hungry :)
