They are located down an inconspicuous hallway right next to Blue Ribbon Sushi. The hallway is covered in really cool old Italian records.
The prices are totally reasonable, and the pizza was great. I had a slice of the white pizza, and my husband had a slice of the sausage pizza & the pepperoni. All three were delicious. Super thin crust, tasty toppings, and they heat it up for you, so the cheese is extra melty.
There are not a lot of places to sit, but it just adds to the big city, pizzeria atmosphere that it seems they are trying to create. The staff was really friendly also. It is definitely worth checking out while you are in Vegas.
