I am heading to Nashville from Boston to take my nephew out for BBQ to celebrate his 18th birthday. I am looking for a good BBQ joint that is not touristy or main stream. I don’t want chain restaurants or joints that have been there forever and have gift shops. I want to go to a small unassuming place that is more about good food than atmosphere and where tourists never tread. One that his parents have never taken him to and never heard of. They have been to the “big” ones. I'm willing to travel within the greater Nashville area. Thank you.
