I voted for Oklahoma Joes. The ribs, brisket, pulled pork, fries & rings, sauce, and they also have a gumbo soup thing I had once that was insane. Good range of everything.
I do consider Jack Stacks a tie with OK joes though, I voted OK Joes because I might have it a tad higher, but Jack Stacks has a better atmosphere and you don't have to stand in an hour long line to eat there.
Bryants I love too, you either love it or you hate it because of the sauce, I'd much sooner send a visitor to Jack Stack or OK Joes.
