I love primanti bros, and this is my neighborhood restaurant where I most frequently stop. I've never had a bad experience here. The food and the service are great and they really have some amazing happy hour deals! The place is never ever empty but I've never had to wait for a table. Staff is good, bartenders are friendly and cooks very competent. I've never had an order that wasn't correct.
Great place to go for a casual meal, and if you don't like these sandwiches then get the heck outta Pittsburgh! :)
