Been waiting a while to try this place since seeing it in TV. Was finally in Pittsburgh and went to the original. It didn't disappoint. The service was great and the food even better. A bit greasy, but that's what your getting into. The ingredients were fresh and it's definitely a city staple. I even grabbed another sandwich at PNC park while watching a game. Can't say much about the other locations, but if you can, head to the original.
