I just moved into the area, and everyone always rants and raves about how amazing Benny's is. I thought it was 100% local just because of how much of a hometown feel is in this place - even though they have other locations, you just feel the Pittsburgh charm of this one. Enormous slices the size of your head. Quick service. Games always on TV. Youthful crowd - which gets pretty loud and crowded on weekends.
Staff is incredibly nice and everyone working there is very charismatic. Makes you feel right at home.
Only real complaint is the $5 slices. It's a little insane. I'm a originally from Bronx, and we have slices just as big for $1 in New York, but hey, the pizza is pretty alright. Overpriced for how it tastes, but it's still wicked good. A definite "must-eat" if you're in the area!
