1. Secret Pizzahttps://www.facebook.com/SecretPizzaLV/photos/2030986220264311
It's not the most accessible spot to discover, as the name suggests, but it has some of the best pizza slices in the city. Secret Pizza sits on the third floor of the Cosmopolitan and features only a counter. After you order, you can enjoy your treat in the lounge area. The best thing about the pizza here is you can customize it with toppings of your choice, and you can buy by the slice or order a whole pizza if you prefer. The pizza is worth every penny and is reminiscent of the classic New York Pizzas.
