Because of your recommendation of Don Obriant's book Back Road Buffets and Country Cafes, I ordered a copy immediately and got it Monday. It's great! I've been to quite a few of those restaurants, and can hardly wait to try some that were new to me.
We're going to Jackson, MS for a few days, and already had the Mayflower on our eats list (broiled seafood platters), but have added Crechale's after reading his notes.
This book will probably replace Jane and Michael Stern's in the map pocket of my car!
