I'm sure I've seen the Rusty Nail, on Buford Highway, before. While I don't get up to that area much, the sign says the place has been around for 34 years, and it's right next to Lawrence's (a Lebanese restaurant that I've been to a few times, over the years).
I'll have to go up there again sometime -- drinking at a place called the Rusty Nail has a certain something. And more bizarrely, driving by today, I saw this:
The photo's not great -- hard to get a good angle, and cars are in the way -- but in the lower right, surrounded by smoke, there's an enormous fake (I hope) gun.
Yeah. There's a giant perpetually-smoking pistol right outside this place.
I really, really want to know why.
Update: as far as I can tell, it's a barbecue smoker.
