Our waitress was not very knowledgeable about what gluten is, but after some conversation she did make very clear what would have the potential for cross contamination. PLEASE NOTE: While they do offer a GF crust, we were told that they are cooked directly on the same brick oven as non-gf pizzas, so NOT SAFE for celiacs. That all said, I did end up eating a delicious house salad with chicken & have not had any issues as a result.
