The back of their menu has about 2 paragraphs on how the staff is trained in cross contamination and how they prevent that in the cooking process. They were so awesome and great to talk with. They even mark each pizza topping on whether it’s GF or not! They also if your lactose intolerant has AMAZING vegan cheese. It was awesome. Idk if some of the reviews here are older calling it not celiac friendly but I can tell you right now it is.
