This is one of those places you really have to visit if you're in from out of town. It just captures the flavor of the local culture beautifully.
I had the cheesesteak which is uniquely adorned with fried and coleslaw to become a "Pittsburger". The sandwich itself isn't all that exciting, but it is good, and it's grilled up right in front of you. My buddy had the ragin' cajun chicken sandwich which was not as spicy as advertised, but he did report that it was good.
Wash it down with a Yuengling, and life is good.
It's ain't fancy, the service could hardly be called friendly, but it's one of those local joints you really have to see and taste for yourself.
