Review of P.F. Chang's

I've always enjoyed eating here, but I won't be back. After waiting for 40 min. (not during a busy time), my order of Mongolian beef arrived with random shrimp pieces in it, which made me really nervous (wheat allergy + celiac). My new order was brought out 10 min later but they told me that they were out of GF soy sauce. So, I waited 50 min for my food, nervous about sending it back, & it's dry with no soy sauce & the beef was so chewy that I had to cut it into small pieces because I couldn't take bites out of it. No manager came by, either, which was an additional disappointment. I expect much better from a restaurant like this.
