Nashville: Loveless Cafe
I know I talked a bit about Loveless Cafe here and the things you can do on your way there and back, but it deserves it's own shout-out. Especially now that I've been here several times, enjoyed their delicious biscuits and also tried more than just their amazing fried chicken (not too heavy, and seasoned well). There's also shops to peruse even when you have to wait a worthy 30 minutes or more for your table. Get some Biscuit Mix, preserves, and more to go and take home so you can take the experience with you.
I like the country feel atmosphere of Loveless and that it's right off the highway in it's own collection of stores and food. I've always had friendly servers here as well that are really accommodating and even encouraging of to-go boxes filled with all the extra biscuits inside. #bonus
In addition to the fried chicken, I've also tried and loved the pit-cooked, slow-smoked pork barbeque plate with their cornbread hoe cakes. Just make sure to prepare before you go and wear your comfiest, stretchiest pants ;)
