No kidding was this place a secret. It literally is not on a map in the Cosmopolitan at all as you are walking around the casino. My guest and I asked two securities guards and they both looked at each other and said "it's a secret.....but it's upstairs on the * floor". I will let YOU figure it out as we swore to not tell anyone ;-). However, it's worth the hunt to find the place. Yes, like any Las Vegas restaurant, it's going to be more expensive, especially since it's inside a casino/hotel. The pizza is amazing though. My guest and I each got a slice and it was more than filling for a snack. The full pizzas are pretty pricey, but if you're hungry, it'd be worth it. Beer and wine is also available to continue your buzz. Seating is limit, but there are tables in the lobby area of the secret location. The final secret I will give is that you will see a hallway of record album covers!
Now go find it!
