Love PF Changs. I always get the vegetarian lettuce wraps, steamed edamame and the Ma Po Tofu for dinner. The wife and I usually inhale the lettuce wraps and then snack on the edamame while we wait for our main courses. They have good tea and we'll usually get a pot of that along with water to drink.
The place is in a bad spot as that whole area of Chagrin Blvd is a nightmare to traverse and idiots abound behind the wheel. Just something to consider.
This place is pretty clean although they keep the mens room heated to the level of a sauna, so don't go in their over dressed because you may suffer heat stroke and pass out. The restaurant itself is comfortable and tastefully decorated.
Service has always been great. I always ask for extra spice in my dishes and the servers always get that square with the kitchen. They keep my water topped off and bring the check promptly when the meal is over, can't ask for much more than that.
Overall, I recommend checking them out!
