This is a Nice, Pizza-by-the Slice place located near the William Hill SportsBook inside the Plaza Hotel. I would rarely recommend a restauant inside a Las Vegas hotel unless it was a buffet. This little Pizza Joint, I would recommend.
It gets the job done. The Pizzas are New York-style. The Pizzas are just baked to perfection. The Cheese is melted just the right amount. The Pepperoni's are baked hot enough to curl upward. So delicious. Slices are around $4.25 per large slice. Definitely not over-priced for what they sell.
One female staffer was not the most polite once, but I've been to Pop Up Pizza multiple times and the other staff have been friendly. Definitely do stop by if you happen to enter the Plaza Hotel in Las Vegas.
