Downtown Summerlin is the perfect place to grab a slice before doing some shopping. Bonanno's is good NY-style pizza. Slices are a little pricey. I had a slice of cheese, a slice of veggie and a bottle of water for $14.
It's a cool spot to eat and people watch. They use good ingredients and the crust is crispy enough to hold the pizza without it flopping over. The slices are a good size. You can fold them or tear it in half.
Bonanno's is good pizza in a fun location, but they are stuck on Strip prices. Bring the price down a bit and this place is a 9/10.
