My wife and I stopped here on a couple of occasions during our stay at the Wynn. The first time we only wanted dessert and opted for the gelato. We've only had gelato a couple times, but this was good and very refreshing on a hot Vegas day.
The second time we visited we had lunch. We decided to split a caesar salad and each get a slice of their New York-style pizza. Everything came out at the same time, which was find with us. The salad was chilled and the pizza was hot, both like they should be. My wife had the cheese pizza and I had the Carne pizza (basically a meat-lovers). They also had soups and sandwiches on the menu, but as the name says they are known for the pizza.
The atmosphere is very casual with about a dozen TVs. There is both indoor and outdoor seating, with the outdoor seating having a view of a waterfall and pond (not the Lake of Dreams like a previous review said).
