Being from the east coast, Pizza in AZ just isn't the same. I hunt high and low like a starved Mountain Lion for good pizza out here.
I prefer NY style. Real NY style. Like downtown, side of the road mom and pop Brooklyn NY pizza. Big slices, perfectly melted mozzerella, thin crust, great sauce. It is hard to find in AZ.
Grimaldi's is definitely one the best pizza places I have found out here. I also recommend Famous Ray's. If you;re looking for good pizza in AZ, you can't go wrong with Grimaldi's.
It is a bit pricey if you like toppings, but worth it if you like pizza as much as I do.
