San Antonio Taco Coa.k.a. SATCO, is a great cheap eats if its all out of your own pocket. Demo's is italian/ameircan style more variety there, similar to a ruby tuesday, or perkins dining atmosphere.

i would cut Nashville from your list based on your criteria, you'd be better off in Memphis you can do that in a day. Dry Rub BBQ, and Graceland is all you need to do. i recommend the speak easy BBQ reasturant if that helps....
