J Christophers you can find anywhere. Try to eat local. Some of the RiverFront restaurants are quite good, even if they are in the touristy area.
If you do not like touristy, you may not like my next suggestion, but Savannah is famous for being haunted. If you like haunted stuff, take a ghost tour of the city at night.
Despite the fact that River Street is where a lot of tourists flock, I like it. I imagine that 150 years ago, River Street would have had a bunch of pubs that were rowdier than what you find today. It is a part of Savannah.
That being said, set time aside to walk to the squares. There are some very good squares that are very enjoyable here. History can be found throughout the city. Make time to walk to and enjoy some of the quiet squares. Sit and imagine others sitting there 200 years ago to take a break from the harshness of life.
Your to see list:
1) The St. John Cathedral
2) If you like churches, there are several worth visiting for their architectural and historical worth.
3) Have a daughter/wife in girl scouts? The girl scout museum and home of the founder (I forgot her name... shame on me) are a part of several museums. When you pay to get in, ask about the package for all of them, which is not much more and pays for itself if you visit two... they did not tell us of this option). You can get a special pin/badge or some such in the store that my wife was excited about. I believe you actually must visit the museum to get said item.
4) Forsyth park is the most popular because of its fountain. Visit some others as well: I cannot stress this enough. Each square has its own history. If you do not want to walk, take a horse-carriage tour. The guides ask about things of interest to you and can take you places you want to see. They are very knowledgeable (and my wife also loved the horse-drawn buggy ride). I found them to be very reasonably priced. You hire them in an area that I think was called the Marketplace that is kindof new.
5) I am not sure if it is there, but there is a wine shop that had muscadine wine from a local vineyard. Do the taste testing there. You will likely go home with a bottle. This was also in the area that I think is called the Marketplace. I may be completely wrong about what it was called, but that is the best I can do for you.
6) If you like literature: Flannery O'Conner's house.
7) There is a really good place to get seafood on River Street. I had hoped that I would remember the name by the end of this post. I did not.
There are numerous old houses that can be toured/visited, there is a square somewhere in Savannah that hosts the Forrest Gump bus bench filming location, and, of course, the Midnight in the Garden of Good and Evil was filmed here (and one of the houses was prominent in that).
If you want to know anything, ask at the place you are staying. They will have brochures for local places, but actually ask. They know the better places to go. Enjoy.
