Also, Gun & Garden kind of scares me too. A lot.

You missed a few:

Hot Fish Sandwich
Bolton’s Spicy Chicken and Fish
Nashville, Tennessee
Most hot-fish vendors fry whiting fillets, stack them on mustard-swabbed white bread, pile on pickle and onion slices, and dribble hot sauce. But Bolton Matthews and Dollye Ingram drag their fish through a hail of “secret” spices that taste suspiciously like straight-up cayenne. Sniff before you bite, and a six-sneeze fit follows.

Fried Green Tomatoes
Arnold’s Country Kitchen
Nashville, Tennessee
That’s craggy Jack Arnold, wearing a foulard bow tie and overalls, shuttling pans of collard greens from the kitchen. His wife, Rose, works the register, dealing butter pats from her cornbread deck, pouring sweet tea by the gallon. Kahlil, their son, a hipster with a megawatt smile, runs his knife through a haunch of garlic-studded roast beef, draping slices onto plates heaped with creamed potatoes and braised collards, spooning oily jus over all. Set in a cinderblock building on the industrial fringe of downtown Nashville, the Arnold family restaurant sets the standard for Southern meat-n-threes. Button-down bureaucrats on a break from paper pushing. Tar-splattered roofers. Bed-headed Vanderbilt coeds craving a taste of home. All slide their trays along the steam-table track, angling for an order of herb-battered fried green tomatoes. Fresh from the oil, sour-sweet, and brittle as can be, they taste like indictments of the lowest-common-denominator norm. (615-256-4455)

And there's also one from BonAqua, which should count as another half for Nashville…
Praise the Lard Biscuits
Beacon Light Tea Room
Bon Aqua, Tennessee
They stew down preserves every week, apple in the fall, blueberry in the summer. Preserves, however, are mere gilding for the biscuits. Silver dollar size and lard cut, they arrive, six to the order, in wicker baskets, begging to be ravished with butter. (931-670-3880)
