This is the Pittsburgh native's Mecca. We all at one point in our lives must make the trip to the Strip district, wait in a really long line, and have an amazing sandwich which is part of our heritage. When it is something you have had all of your life, you can't disparage it by giving the restaurant less than 5 stars.
So why are some of the reviews 1 star and 2 stars? I guess some foodies expect a Tom Colicchio quality sandwich for the whopping $4.95 they are forking over. I think you can only expect so much in way of presentation at this price point and need to reflect on the heritage of this fine institution and the part it plays in Pittsburgh culture.
