They will make nearly any pizza gluten free. The only exceptions are any with items that are not in themselves gluten free. Meaning you can't get the pizzas that have gravies etc because the gravy is not gluten free. Most of it is common sense stuff like that. There's also the risk of some cross-contamination although they do make an effort to lower that risk. I have to say my least favorite thing though is seeing everybody's faces when they get the gluten free order. They follow the rules but nobody's happy about it.
