I recommend avoiding the circus circus pizzeria. There is a reason why one has to pay up front. It is to avoid any other interaction with staff after receiving a sub par product. The location is high volume. I don't mind waiting, but was very disappointed. The pizza was flavorless with low quality ingredients. The truly frustrating facts was that the pizza was not   Cut all the way into slices. The cut was only partially visible in the cheese and did not penetrate to the crust.  There was no one available to resolve the situation. A major let down considering we payed 40 dollars for two medium pizzas. Another annoying aspect were the trick tea urns. They are designed to look like fresh brewed ice tea, but the spew syrup from a box. If you are looking for descent pizza on the strip, try the pizza by the slice at treasure island.
