Located on the Country Club Plaza, P.F. Chang's is a somewhat upscale Chinese restaurant (for a surprisingly non-upscale price) that offers a large and tasty vegetarian/vegan section on their menu. Try the veggie lettuce wraps and the coconut-curry vegetables. If you're looking for a place to eat on a Sunday night, P.F. Chang's is always a reliable and yummy option.
P.F. Chang's won a PETA 2005 Proggy Award for North America's Best Vegetarian-Friendly Restaurant Chain: "P.F. Chang's China Bistro is the future of dining in America. The rapidly expanding chain's ambience is hip and upbeat yet relaxing. Twelve tasty vegetarian items are clearly marked on the menu for easy identification, and the restaurant will customize any dish for vegetarians and vegans. Firm, marinated tofu is gladly substituted for meat in any dish—our recommendations are too long to list, so check out the nearest one for yourself!"
