The most mediocre pizza place in the most mediocre food court in the most mediocre hotel in Las Vegas.
Before heading to Sbarro, which is located in a basement food court of Bally's Hotel, ask yourself? Am I hungover? Do I need this food so I don't die? Unless you have answered yes to either of these questions, do not proceed to eat at Sbarro.
There's a reason these places are only in food courts. Because nobody with transportation (car, bike, train, jet pack) would actually stop here. And there's a reason they have gone bankrupt twice - the food is bland and overpriced.
Seriously, two slices of pizza for like $10 and a Gatorade for $3.50? I can get two pizzas and two gallons of Gatorade from Little Caesars for that much.
Pass on the Sbarro and pass on this entire food court. It is not worth your time.
