I'm more of a pulled-pork connoisseur myself, not really a rib fan, so I'm busily taking notes.
Swallow in the Hollow and Dreamland sound interesting; I hadn't heard of those two before.
I'd considered trying Shane's Rib Shack at some point...now I have one positive review (here) and one negative review (from a sometimes-overfinicky friend), so I'm leaning toward trying 'em soon.
Any of you Southeastsiders remember a place called Jimmy's Smokehouse BBQ? They used to have a roadside shack somewhere near Conyers and were awesome....I never actually saw the shack, but at one time they were catering our night-shift at work and it was really splendid BBQ and southern fixins'. They may still be in business, but they had to drop our catering when they got a NASCAR contract. (Good for them, sucked to be us.
)
I remember going to a decent BBQ place called JR's up in Peachtree Corners that was good, but I've only been there once.
Corkey's on Pleasant Hill (I'm assuming that was a chain?) was decent, but IMHO overpriced. Apparently, my opinion was shared by others, since they're gone, gone, gone.
