I asked about the prep process and was told the crust comes premade and frozen. The same prep area is used, but put on clean parchment paper. There is no separate sauce or toppings, though they will change gloves. If you aren't super sensitive, you may be ok. My son with a wheat allergy was ok, but I was ill for days. All other foods I had prior to this were prepared by myself, so I am sure it was this pizza.
We wanted to dine in, so pizza delivery sounded good. My daughter has food allergies - gluten and dairy. When I placed my order, I ordered her gluten free pizza with no cheese. Order was read back to me. When all of the pizza arrived, her pizza was loaded with cheese. Deliverer checked the order and saw that it was wrong. He went back and got the correct pizza. All of the pizzas were ok.
