Steve and I did get to speak to the manager, Christina,whom was very knowledgeable about not only the gluten free pizza but also the gluten free lifestyle. It was very refreshing to go to a restaurant and find staff that actually knew what they were talking about. I have only found this in a small number of establishments and I was very pleased to find this at NYPD.
Christina explained that all of the gf pizza is not only prepared in a separate part of the kitchen but it is made in its own oven. The crust comes from Still Riding and I can vouch that the crust does not come apart easily and it is very delicious. If you are out of delivery zone, like me, you can order the pizza frozen with your desired GF toppings (only some toppings at NYPD are gf) and you can take the pizza home to cook. The pizza tastes best fresh from the oven.
I would definitely recommend NYPD to all my fellow gluten free enthusiasts. If you are in AZ, I suggest that you try it!
