Secret Pizza is a lovely hidden gem on the 3rd floor of the Cosmopolitan. There is no sign outside the restaurant so your best bet is to ask someone where you can find it. Once you see a hallway filled with pictures of album covers follow your nose straight ahead to the scent of the pizza! We went at 6pm on a Saturday night and this place was super busy. They have a very limited selection of pizza and beer including Bud Light on draft. Cheese pizza starts at $5 a slice and you can add more toppings if you wish. You can also order a whole pizza. They have a small standing bar area with two stools so there is not an adequate seating area to sit down and eat. Pizza is NY style with big, foldable slices. The crust is chewy and delicious. Give it a try!!
