Just saw this!
Easy Nashville has the best artsy/coffee shop/bar scene. Barista Parlour for coffee and 5 Spot/3 Crow Bar/ Mickie's for a dive bar environment.
I usually like hanging closer to downtown though. Pinewood Social for apps and drinks (and bowling!), Crema for coffee, Two Bits for a great barcade.
If your near the south, check out ML Rose and 8th and Roast.
