This place is probably 3.5 stars, but as Yelp doesn't allow that I rounded down to 3.
I had a slice of their mushroom pizza - which costs $5.50 hence the name of the place. It was decent, slightly salty and plenty of mushrooms. The crust was a bit chewy and thicker than I like.
The price was reasonable for the quality of food, but really if you want the best slice in Vegas then you have to find the "secret" pizza place in Cosmopolitan and have a slice of the white pizza - amazing!
