It’s not often that pizza makes me think about pro wrestling, no matter how well the two go together. However, after dining at one of the hidden gems in Las Vegas’s pizza crown, I’m reminded of something “Rowdy” Roddy Piper said to “Y2J” Chris Jericho in the buildup to Jericho versus The Legends match at WrestleMania XXV. With a serious look on his face, building the tension for the upcoming battle, Piper stared Y2J down and told him, “Old school is cool.” The words of the late, great Hot Rod ring true when it comes to Old School Pizzeria, one of the best pizza places in Las Vegas in one of the unlikeliest of locations.     Sitting in a small strip mall on Craig Road across from the Cannery Hotel, OSP serves sophisticated pies that are as scrumptious as they are smart.

Combined with tomato, cucumber, onion, fresh mozzarella and a nice vinaigrette, it’s herbaceous, clean, and a perfect starter. After our good luck with the first “chef’s dish”, we continued down that path with our pizzas. Instead of going traditional, we opted for the Chef’s Pizza Creations which run anywhere from $18 for a small to $45 for a large. They are worth it. My stance that black olives often take away from a pie instead of add to it is well-documented. The Classic Combo proves to be the exception to the rule. Caramelized onions, roasted bell peppers, roasted mushrooms, house made sausage, and pepperoni join the black olives for a familiar creation.
