The name I see most frequently with regard to Las Vegas is Metro Pizza. I would say their style of pizza looks most like a New York style, but is sort of a hybrid between New York and American, leaning towards a slightly thicker crust. Reviews I have seen are typically in the plus column, but mixed. Folks seem to really think it is the bomb, or it is a bomb (literally). Take your pick. I, personally, have not tried their pizza, but you can find photos on the internet from places like Google Images.
