Review: Houston does not have any REAL vegan options for pizza currently. I mean, you can order pizza with no cheese and add your fav veggies, but Zpizza is the only establishment that actually offers DAIYA VEGAN CHEESE, which I will forever be grateful for. But on the other hand, I'm not sure if I will be returning because I watched them prepare my vegan pizza and slice it with the same slicer they use for pork pepperoni and sauasge pizzas. Call me ocd, but I have a BIG problem with my vegan pizza being prepared so close to pork products. When I inquired, they said that they wipe the blade before slicing into vegan pizzas, but would it really hurt to get a seperate blade for veggie pizzas? Overall, if my options were super slim, and I could not eat a homecooked meal, I would go back if I were desperate for the closest thing to a vegan meal. The people are friendly, but the pork and meat products are too close for comfort to me. For taste, I would give them four stars, especially since they are the only ones that currently sell vegan cheese pizza in Houston. (besides Whole Foods).
