They use daiya and if you order the lunch special, they will substitute romano cheese for another topping.. which is ideal! The most important thing to me is how delicious the crust and tomato sauce make the pizza.. I can whip up a decent homemade pizza with daiya and homemade sauce but a 900 degree, important Italian pizza oven really can't be beat..
My father insists on visiting Famoso every time he visits me, he's a big meat eater so I would recommend Famoso to someone with a family that doesn't compromise their habits.. and anyone really. It's delicious pizza.
Also, vegan gelato. Do it.
