I have Celiac. Round Table is my go to. They ALWAYS triple check the crust. I had a snafu with online ordering. It failed to tick the “gluten free” box. When I arrived they fell all over themselves remaking it and even gave me a beverage while I waited. They truly are celiac friendly and it is really good pizza.
We ordered delivery. The menu states the 9.5" is available with GF crust, in the actual order website it didn't list GF as a crust option. I put it in the notes and asked them to be careful. When the pizza delivered, the first words from the driver person were, "Everything was prepared separately and there was no cross contamination. You should be safe and healthy eating this!" She was absolutely right. The crust was tasty, the pizza very good with lots of fresh toppings, and no issues at all. They clearly took it to heart and were careful with the prep. Very happy!
