The following review is based on an actual conversation (if by "actual" you mean "embellished for literary panache").
"Primanti's is the best! It's a Pittsburgh institution!"
"It's terrible. The sandwiches are over-rated. It's a novelty act!"
"Screw you!"
"Bite me!"
"I can't believe I married you!"
"I can't believe I ever asked you to marry me!!"
This type of argument seems to abound on Yelp. So just try Primanti's and decide for yourself. I do agree that the cheesesteak isn't that great, but I would highly recommend the capicola. The spiciness of that meat works well with the coleslaw.
