Located on the 3rd floor of the Cosmopolitan, I'm not sure how much of a "secret" this place is anymore. Well at least for those of us who live here. I've been here a few times now and each time have really enjoyed my experience. It's nice after a show or having met friends on the Strip to just run in and grab a slice. Most of the time that's all I'm really needing anyhow.
Once you get down the hallway you walk into what looks like any slice pizzeria I've ever been in. You wait in line, order up a big slice of whatever they have made in the last 10 minutes, and find a little counter space to enjoy pizza and wine/beer.
Every time I've been here they I've gotten through the line quickly, the staff has been friendly, and the pizza has been good. It is a bit pricey for a slice but you're on the Strip so that's what can be expected. If you weren't being overcharged then it wouldn't be a Las Vegas restaurant.
All in all I like this place and will probably stop in again if I'm dragged to the Strip.
