Thought PF Chang was pretty average and certainly overpriced, though the portions are quite generous. Dumplings were quite nice and most of the dishes we had - ginger chicken, chilli beef, chow mein - were decent if not spectacular. The menu is not very exciting, just standard dishes delivered to a good standard. Much better Asian available in Panama. The decor is quite nice but there are too many tables stuffed in and generating atmosphere in multiplaza is a challenge.
