DH and I are on a two day whirlwind road trip down through Nashville, Chattanooga, Atlanta, and into Florida down to Broward county. (Long story, don't ask.) However, we figure we are entitled to at least eat a couple good meals on the way.

We are taking Highway 24 through Nashville and Chattanooga, then 75 through Altanta down to the Florida Pike south until we hit Broward.

Any eating suggestions relatively close to the highway? Informal and not a lengthy meal (but tasty) would be best.

Note that we will hit Nashville in about three hours, so speed counts. Thanks in advance!!
