The taste was not so great in my opinion.
Last time we ordered gluten free pizza it was burnt. Admittedly, gluten free crust is typically thin and easy to burn. This, however, was too bad to eat. When we asked them about it, they asked, "did you ask for it not to be burnt?".
I have been a few times and have celiac. I really line their pizza. the girl told me they make it in a separate pan and use different utensils to cut it. I've not been sick. as for the size I think its perfect. I think the price is good to. its the cheapest around and I feel its a fair price. I couldn't eat the entire pizza on my own.
