I would recommend looking up Dukes, as that is the original facility. also, if you are trying to find an actual Corporation, I don't think they fall under that category. They only own Dockside Willies, dukes, and rock bass. It's not exactly a chain. Seriously, I would just walk upstairs in any of their restaurants and look for the office...
They're headquartered out of Rockbass Grill: 461 South Front Street Wormleysburg, PA 17043
I'd simply suggest calling and asking. They own a number of places.
