In my neck of the woods. Smokejack in Alpharetta is good (love their Porkzilla sandwich). Also 'Cue in Milton is good - love their Brunswick stew.
Smokejack's is great. Great people too, the owner (or manager, not really sure) drove my buddie's (elderly) grandparents all the way home during the snow storm last winter.
Also, Two Brother's in Ball Ground has amazing pulled pork and home made ice cream. //letseat//
