Gluten-free review:
I got the white top pizza on a gluten-free crust, which is an extra $4. Most places charge an extra couple of dollars so this is on the pricey side, but the crust is delicious and worth the splurge. You can build your own pizza or get a preset one like I did.
Everything is made in front of you ,except the crust, which is pre-made, and they put it on a black pan instead of the wood fibreboard the other crusts are put on. I'm not sure if this is to reduce cross contamination or because of the way the gluten-free crust has to be cooked.
When you order and request a gluten-free crust, they ask you if the request for no gluten is an allergy or a dietary choice. I was the first one there so they had put on new gloves and new toppings, but if you order after people have been served there might be cross contamination. They use a ladel to scoop sauce onto the pizza and then use the same ladel to spread it on the crust and then put the ladel back into the pot of sauce, so if you have Celiac's disease you may need to request that they apply sauce from a new container.
Overall the pizza was delicious and I didn't have any reactions to it. Note that I have a gluten intolerance and can manage with minor cross contamination.
TL;DR possibility of cross contamination
