I stumbled upon this gem after reading about in the Wednesday Food section of the Review Journal about 4 years ago. Back then it was located on Horizon Ridge and has since moved to it's current location. Back then I thought it was the best pizza in town so it's nice to see that they have done well enough to relocate to some prime real estate in The District.
This isn't your typical New York or Chicago style pizza. It is classic Naples all the way. Settebello uses the freshest ingredients and has by far the best crust I've ever had. There are numerous house special pizzas you can order or one can make their own including any number of toppings. The pizzas are delicious and the perfect individual size. You can eat a whole one without feeling super heavy after.
If you're in Vegas, you have to stop by Settebello. Whether you're a local or on the strip, it will definitely be worth your while.
