I had a thai chicken salad while on a lay-over. It was tasty and healthy and caused no symptoms, so presumably safe. Also, large servings - I got the small size salad and it was plenty big for me. They have an allergy button. I didn't ask about pizzas, but given the small space, it seems unlikely they'd be celiac safe.
