It's one of my top go-to places for Chicago-style hot dogs. (Remember, kids - there are *seven* condiments, and not a single one of them is ketchup! ^_^; )
A Chicago dog and fries are always a great deal, and it's nice to see a place that has RC Cola and related brands on tap. (Something you don't see every day, but then there's a good distributor in the area, so I hear.)
Parking around the place is somewhat limited, but it's all in timing your visits. I've yet to be there when the place is packed. Luck of the draw, I guess.
When I hear that folks from Illinois (Whether visiting, or relocated) stop by, then that clinches the deal there. (I'm an ex [or "exiled"] Californian, but I have appreciation for a good Chicago-style dog.)
