We saw many review of Pizza Rock and had to make the stop on our last Vegas trip. The inside is very quirky and fun. It has a definite metal/punk vibe which cool.
The pizza menu is extensive...almost every type of style you can imagine. We tried a more traditional thin crust and it did not disappoint. It was a bit greasy but you sometimes a great pizza needs it!
The restroom signs are probably some of the funniest I have ever seen!
