This place is the real deal. I can't claim to have discovered it - John T. Edge has written of it before, it's been mentioned on these very boards - but I will happily shout its praises to anyone who may be driving down I-95 between Savannah and Jacksonville.
The buffet appears to be one of the exceptions to the rule of buffet avoidance - fried chicken, roast beef, ham, plenty of good southern veggies, all quite good. Our kids went that route, while my wife and I shared the bountiful seafood platter, enough to feed a family of four. The fried wild georgia shrimp were excellent. The fried oysters were big, juicy, fabulous. Stuffed / deviled crab kept you happy. And the fried fish was perfectly done.
I can not recommend this place highly enough - get down there, a few miles off I-95 in Darien, GA, a cute little fishing town with plenty of character. The locals got it good in Darien, GA, as long as they're at B&J's.
