I was recently DXd and was super happy to know that Urban Bricks was GF friendly. I had the Cauliflower crust and 3 little piggies toppings and didn't have any troubles. It was actually really good and the guys that were working that day were super helpful and friendly.
Ordered a half white shroom on a gluten free crust and no reaction. The gf crust is vegan. They also offer a cauliflower crust that is gf, but mixed with some cheese so not vegan. To help mitigate cross-contam, they scraped the oven before making mine. Everything is baked in the same oven so your reaction may vary since it’s not totally separate. Overall it was a good pizza. Felt doughy even though it was gf. The white shroom has always been my favorite, even when before going gf.
They have gluten free pizza crust and vegan cheese, which is great, but the crust was not very good. More like a tortilla that was burnt on the edges.
Having gluten free options is awesome. Pizza was delicious. My non-gluten free son had the Big Daddy Mac and said it was “sexy”. I think that means unbelievably good.
