It is by no means the best pizza I have ever had, nor is it the best pizza by the slice, but I personally love the idea that they don't advertise, and you have to walk down a little hallway to get it. \n\nThe novelty of this place is what earns it four stars. Knowing about this little place makes me feel like I'm part of an exclusive club (or at least a club that 187 other yelpers know about). \n\nI tried the mushroom and white pizza. Both were delicious thin crust style pizza. The mushrooms on top my pizza were particularly delicious. And at $3-$4 a slice this is probably one of the best deals in Vegas, and definitely the cheapest meal that I saw in the Cosmopolitan.
