I like secrets. I like pizza. Its only natural that I would like them combined! Secret pizza is the pizza by the slice joint on the third floor of the cosmopolitan. There's no sign, so you'll either have to follow your nose or look for the hallway line with framed records and pictures of musicians. Once you find it, head on in. We had the white slice with pepperoni and the meatball ricotta slice. Both were SO GOOD. I love the crispness of pizza by the slice and secret pizza really crisps it up. The white slice was good, but the money was really on the meatball ricotta. The missus really summed it up... its like eating a slice of lasagna. It's the perfect end to a late night and is pretty much the same price as pizza by the slice at home. Give it a try!
