The thing about Pizza Rock isn't just that it's good pizza. There's now, amazingly enough, a lot of that in Vegas. The thing about Pizza Rock is that it isn't just one kind of good pizza, like New York style or Napolitano, or Sicilian or whatever. Pizza Rock has them all, and does them all well--as well as their own creative twists. You can get a classic wood oven Napoli Margherita and your friend can get a classic slice of New York with sausage, or Roman, or Californian or whatever. Good beer selection too.
I think they have live music on the weekends...
