Great place hidden on the 3rd floor of the cosmopolitan near the Pool and board game area, you can find it my going down the small hallway with album covers adorning the walls. Very low key old school vibe, reinforced by the pinball machine and old school arcade machine.
The pizza here is great, if your planning on feeding 3 or more people (or two very hungry people) I would recommend just buying an entire pizza, they make it right in front of you and is way more cost effective.
The service and attitude of the employees is great, which is good because of the six times I went there, I was drunk twice and DRUNK once and they still put up with me.
They have a small beer selection as well which consists of PBR (yuck) and dogfishhead IPA (yum), and I believe their menu even has a entry that says "slice and a beer" or something to that nature.
Overall, a great place to start or a end a long night.
