I know it's a Pittsburgh classic, but the place is honestly a bit overrated. I don't eat meat, so I always get the Egg and Cheese when I go to a Primanti Bro's, which isn't ideal, because I'm also lactose intolerant. it's rough. Wish they had more vegetarian options.
I went at about midnight after a flight from the west coast, and the host stand was empty. I ended up seating myself because no one was around; the servers were all too busy trying to close early.
Food was average, I guess. I'm not a fan of their fries because they always seem under seasoned and soft. The bread also just can't hold the sheer amount of stuff on the sandwich. The coleslaw is always great, though. I guess it's something good to have at midnight, when you're too exhausted to care what it tastes like.
