P. F. Chang's, while part of a chain (I admit to an inherrent distrust of cookie-cutter chain restaurants), is a fun restaurant -- especially if you go with a group. I would recommend dining with a group so everyone can sample a variety of dishes.
Even though P. F. Chang's is a chain, the food is very good to excellent and doesn't taste ordinary. The menu is quite extensive, so be prepared to spend plenty of time browsing the choices. I would definitely order an appetizer. The chicken lettuce bundles are especially good if you've got a crowd. For the entrees, I am partial to the seafood dishes. Be careful with the spicy dishes -- there have been a couple of times I've ordered spicy dishes that poured on the heat a little too thickly (and I am not someone who is averse to heat). Be prepared for the condiments they bring as dipping sauces, which include a couple of dipping sauces and vinegar so you can adjust the sauce to your personal taste. I have to admit, however, that I almost never use the sauces. The foods are always sufficiently flavorful for my tastes without having to add on.
Be sure to have hot tea. P. F. Chang's offers a good variety of teas, and it's served up piping hot in a personal iron tea kettle.
Service is friendly, and usually quite efficient. I have never found my servers to be cloying or annoying. The only downside is the LONG waits during peak periods. P. F. Chang's is not recommended for pre-concert dining on weekends -- you can expect a wait of 30 minutes or longer.
The restaurant is beautiful with its statuary and comfortable seating. The lighting effectively makes the restaurant seem more intimate than it is, given its size. Seating is very comfortable, and you're not crowded. Be prepared for noise at busy times.
Pros: Good food, good location in Utica Square, extensive menu
Cons: It's a chain. Be prepared for LONG waits at peak times.
