The staff does warn about risk of cross-contamination due to wheat products in the kitchen. However, I advised them I was a coeliac and have eaten safely at other zero95 venues. The pizza did not disappoint with no adverse reactions. It has to be one of the best gf authentic pizzas out there. The dough is light and fluffy, but only one size available and they do charge $5 extra but that's great for such a treat. And there is a gelato shop (Meno Zero) next door with some gf flavours. Yum!
