I know every mall has a Sbarros and I'm surprised to find one in Ballys. Average pizza for a good price compared to Serendipity outside Caesar's Palace which is highway robbery.
Great for the traveler on a budget.
For quick access to Sbarros without stepping foot in the casino, just keep walking past the valet to the side of the building along Flamingo Blvd and you'll see glass doors that enter into the basement and it will be straight on your left side along with other fast food chains.
