Staff are knowledgable about cross contamination and gluten sensitivity. However, be very careful ordering...there is a specific plate that they serve gf food on. I went twice to the Downtown tempe location and was given non gluten free singapore noodles, all night i was sick in pain. When i called the manager, he did absolutely nothing about both incidents. Horrible manager here not safe for celiacs and over priced for something thats already gf. Pick another Pf Changs if u have celiac or an intolerance. Downtown tempe definately not a good option.
