The staff was very knowledgeable about the GF items and even had a list of pizza crust ingredients (I am extremely allergic to nuts and coconut which commonly replace gluten flours). The pizza crust was incredible. My family said they would order all the pizza GF next time as they liked the crust more than the regular. There was a $4 charge for GF crust but well worth it. I am gluten intolerant (not celiac) so I did not ask about cross contamination of the pizza ovens.
