Hands down, BEST PIZZA IN LAS VEGAS. If you like New York style pizza, then you'll absolutely love this place. I saw some negative reviews, and I honestly don't understand how someone could not like this place. (they must be the type that thinks frozen home pizza is the best, LOL) Since I tried Old School, I can never enjoy a pizza from anywhere else. I'm always disappointed and think "I wish I had Old School instead". Unfortunately I no longer live close enough to get it as often as I use to. Hopefully sometime in the future Old School will have a chain, one of the locations being in the Centennial Hills area. HAHA, I know unlikely, but a girl can dream right? ;D
