Didn't there used to be a Chicago-themed restaurant on the Mobile Street Plaza in downtown Florence? Is it still there? I never got a chance to go, but seems like I heard that they specialized in hot dogs. Maybe I dreamed that. For my money, I was always a fan of both Bunyan's and Trowbridge's.
If any of you are ever here in Chattanooga, I suggest a place called "Good Dog" on the North S****. Definitely one of the best dogs I've ever eaten. There's also something about the dogs at a baseball game (along with an ice cold beer, of course).
