Since it's the holiday season I would call ahead to check on these but normally:
1st Saturday of each month Winchester TN (BGF) has their EAA breakfast. If the weather is good expect 50+ airplanes... it's popular. They usually have a good price on fuel also.
Livingston TN (8A3) has a courtesy van and there is a very good sandwich shop downtown.
Tullahoma TN (THA) has the Beech Museum. Well worth a visit! The FBO has a courtesy car and can recommend restaurants. Two grass strips available.
Houston County (M93), mentioned above, has Southernair Restaurant across the street. I haven't been in a while but it used to be good.
Howenwald TN (0M3) has a courtesy car and can direct you to the Junkyard Dog Steakhouse. One of my favorites.
Sikeston MO (SIK) Lambert's Cafe, home of the throwed rolls.
The gang I hang out with, The ROMEOs (Retired Old Men Eating Out), goes to Centerville TN (GHM) on Tuesdays, weather permitting, to graze the buffet at the Homestead Restaurant. I left my airplane in Alaska for the winter so I'm bumming a ride these days but if you are there by 11:30 you are welcome to join us. If you prefer solitude and go any other day of the week just be sure to bring back a snack for Gus, the airport dog. He's particularly fond of the chicken livers.
Murfreesboro TN (KMBT) where I have wheels..... let me know when and I'll pick you up and take you to lunch... or breakfast if you like getting out early. I'll pm you my number.
Happy Flying
