Have not had the oppurtunity to check those listed out but back when i was still driving cross country i found a lot of mom and pop places and little out of the way spots with really excellent food. Most but not all of the little good food spots was down south.

Found a small unadvertised resturant on the Fl/Ga border on I-75 that had the BEST catfish and eggs and hush puppies i ever ate.

RIDE SAFE.
