My wife and I visited this P.F. Chang's recently. We enjoyed our visit and enjoyed our food. Two things distinguished this from other P.F. Chang's we have visited: (1) the tables seem more crowded together (and since they all were full I presume that is because of the place's popularity); (2) they were out of the first three bottles of wine we ordered. I tend to view chains negatively, and Chang's does nothing to dissuade me from that. I am sure there exist good analyses of American chains doing ethnic foods, and I will let those speak for themselves. The chain obviously is enormously popular, and this one does what it does well.
