iirc, the second oldest synagogue in America is there. It's a gorgeous bit of gothic architecture that's worth a visit even if you're not a member of the tribe. The historic district is where most of the old school charm and entertainment are. Great for just walking around and seeing what you see. If you've not seen it, watch Midnight in the Garden of Good and Evil to give you a flavor of some of the city, which is a central character in the movie. I'd recommend restaurants, but all the ones I liked were southern comfort food and incredibly unlikely to be kosher. I wish I had been using FourSquare/Swarm when I went in 2006 or I could give you the entire itinerary and hotels. I stayed in a different bed and breakfast every night in the historic district which wasn't bad since they were all within walking distance of each other. Definitely an experience.
