I'm coming from SoCal where we are having this big custom pizza craze, it was nice to try something similar out in Vegas. I stayed at MGM and this was a great place to grab a bite. I wish it was located in the main food court instead of the Underground where it's kind of hidden away. I feel like they would have more customers being located elsewhere.
The workers are super friendly and love to chat you up. Essentially a full fledge custom pizza place. You can even make a dessert pizza. You customize first, they bake it, and put it in a pizza box with your name. One tip is that, you might not want to load so many toppings even though it seems obvious to do so. The pizza might not cook as well with too many toppings. Price was fairly reasonable as well. Really tasty and a bit less oily compared to your normal pizza hut.
