Disclaimers, I guess: I was here on St. Patrick's day and the line was long and rowdy, and we took our food to go since there was no seating. I had the kielbasa and cheese sandwich, and by the time I got to sit down and enjoy it probably 30 minutes had passed. The kielbasa was good, the coleslaw seemed good, but overall the sandwich as a whole did not live up to the hype. The French fries weren't anything special, and they honestly didn't seem to add anything positive to the sandwich. I had some cheese fries too, which were soggy and the cheese had practically no flavor.
It's possible I'd enjoy the food more if it were fresh, but I don't think I was impressed enough to return the next time I'm in Pittsburgh.
