The name of this restaurant characterizes this place perfectly. No one knew where this thing was until we entered into the building where it's located, The Cosmopolitan. Even then, the directions we received did not lead us to the restaurant but merely to the general vicinity. It's located on the 3rd floor and looks like a hallway. It has no signs, advertisements, etc. You just walk down the hallway with all the pictures on the wall and viola! A pizza kitchen! You might also spot people coming from the "hallway" with paper plates lined with checkerboard foodpaper.
Excellent pizza, and at a good price, especially for Vegas. We had the pepperoni pizza and "white slice". Would highly recommend both. I wish I had tried the sausage and pepperoni! Enjoy!
