Definitely gluten free. I had the choice of 3 different 10" crusts, all of which were mostly cauliflower. It was very good, but I would not call it pizza. More of a flatbread type cracker thing. And I've eaten a lot of gf pizza. The waitress said she'd never had a gluten complaint and they cook the pizza in the oven, but on its own little tray or foil or something. Good food. Not pizza, but good.
