Do not bother. I understand if they are open later than most restaurants and/or pizzerias on the strip but that does not justify the 18.00 dollar price tag on two sub-par slices.
Actually, the slices are not even as good as many dollar slice spots I know of in NYC!
Stay away! I am only giving the 2nd star for convenience ( and they do not even stay open all-night...if we arrived 5 minutes later they would get 0 stars).
