As a grad of the U. of Pittsburgh, I gotta tell you that the Original Hot Dog Shop is known around campus as the "Dirty O." Now I won't say it's exactly dirty... shabby would be more accurate.
The hoagies and cheesesteaks have a great reputation, but the hot dogs are its namesake. Where else can you ask for your dog medium or well-done? But the real deal at the Dirty O is quantity - an excess of chili, cheese or onions on that dog. And the fries! A small order of fries covers a typical cafeteria tray - no lie. They're good and hot, if not the most elegant plate of Belgian style pommes frites you ever ate.
Take a place in line at the hot dog station, move on back to the hoagie and fries station, and stop at the beer station. Pretty soon you've got a trayful! When you consider the quantity, the price, the beer on tap or in bottles and the extended hours, the Dirty O is the late evening place to go for another round and a satisfying meal on a budget.
