Mention Bar-B-Que and it is easy to get an argument among true afficianados who have their favorite place. I love Bar-B-Cuties in Nashville, especially their old location on Nollensville Road near Old Hickory where they smoke the meat. Many local's swear by Jack's and I have enjoyed it-- though I still have my preference. your choice?
I have only tried Jack's and Corky's, but if there were a Jack's in Louisville, I'd be one fat SOB! I love it. Jack's is my all-time favorite. When we go on vacation, we have to time our drive right so that I can stop in Nashville for some Jack's.
Marys over on Jefferson Street, better go there for lunch, not very friendly after dark. Use to be a place over off North First & Cleveland ST. Cantrells. They use to have some really good BBQ sandwiches.
