I'm still a newbie when it comes to Nashville having only been there twice, but one thing I've gathered is that Belcourt Taps is about as authentic Nashville as you can get.

De Oro Mine Co is an awesome dive bar in Spring Valley, CA (a suburb of San Diego). No contradiction there - although it's your typical dive with cheap drinks, billiards and sports on TV, the vibe is on point. There's a reason for that - namely, the owner Wayne 'gets it.'
