RE: Atlanta to Indianapolis I-75, I-24, I-65
The Kreme House, exit 11 on I-75 in Ooltewah, TN is an outstanding roadfood spot. Excellent downhome food, friendly service.
Also, there are a couple of Dinner Bell restaurants located closer to Knoxville, around Sweetwater, Lenoir City that I've always wanted to try but never have. Maybe Sundancer could comment on this.
