After a night full of drinking and gambling in Sin City, where do you go to get some delicious food after midnight? SECRET PIZZA. Located in the Cosmopolitan, finding the little pizza parlor is an adventure in itself. Secret Pizza is located at the end of the corridor by the pool tables. There are no signs for the entrance which makes it a bit difficult to find. I would definitely recommend the white slice, then adding a meat such as pepperoni. They do offer pies as a whole for sale as well. One big advice: avoid going to Secret Pizza around 3AM on a Friday or Saturday night.... All the club crawlers from Marquee want pizza too and there will be a long line.
