On a recent visit to PF Changs at the request of a friend, we encountered very mediocre Americanized Chinese food. The noodles were burned and over-sauced. The chicken was very salty, and the beef was very dry.
We did provide this feedback to our server, who then escalated to the manager, who was nice enough to comp our meal, but I won't be back ...
If you want authentic Chinese food, head to Cafe Ori in nearby Redmond. You get top quality food in ample quantities and at very reasonable prices.
