I have been to 3 P.F. Chang's in my lifetime and this is my least favorite. Just took my girlfriend there this weekend for her birthday celebration, and P.F. Chang's was the worst part of the evening. Now don't get me wrong we had an amazing evening so in retrospect P.F. Chang's was A-OK.
I suggest making reservations especially on the weekends this is the busiest one I have been to. The hostess wasn't that great took an hour for us to be seated even though I made reservations. Was not happy, the great thing was the food here. If you don't care about eating bad food for you get the lettuce wraps they are delicious. I had the ginger chicken and broccoli which was great also. Very large portion sizes for dinner be aware.
The atmosphere was beautiful, but if you are looking for something intimate or romantic stay away just way to loud and open for that feeling. I suggest going to the P.F. Chang's in Phillips Place personally. Not as many kids, more of a adult feel.
I would suggest P.F. Chang's anytime, just maybe not this one based on the situation.
