I miss Rally's from Michigan. Sonic is about 45 Minutes from where I live now, and not worth the trip, IMHO.
I was a big fan or Hardees as well, loved the Frisco Burger. None around me. National Coney Island, Michigan, as well. Love me some Coney Dogs with Cheese!
Favorite All Time though....
Ted's Hot Dogs, Syracuse and Buffalo Area. Char Grilled Dogs on toasted rolls. YUMMY!
Dairy Queen. 'nuff said.
I used to own a piece of propert in Satellite Beach, FL that had a Dairy Queen on it. Their "fast food" was definately better than most.
