There are many pizza joints popping up now in the middle of the Las Vegas Strip. From Secret Pizza (Cosmopolitian) to Five50 Pizza Bar (Aria) to Sbarros (everywhere lol), you have your choice of pizza selections all over.
But I would be hard pressed to find a better pizza combo deal than the one that exists at Pin Up Pizza, located in front of Planet Hollywood. For $9.50, you can have any slice + garlic knot + fountain soda. Just say to the cashier, "THE SANDRA D COMBO PLEASE".
I choose the meatball pepperoni slice as part of my combo. Even though it is not authentic New York pizza, it is still pretty darn satisfying considering it's price. The slice is HUGE too. The real winner of the pizza combo is the garlic knot though. It's the best garlic knot I have ever had; even better than the ones from New York.
If you are trying not to break the bank in finding a inexpensive lunch on the Las Vegas Strip and you don't want to eat panda express or McDonalds, definitely try Pin Up Pizza. You will need that oily pizza grease to soak up your alcohol intake at the end of night ;)
