My husband and I will be in Charleston for only one day next month (I know it should be longer). I would like lunch sugggestions concentrating in seafood and southern cuisine. I think we will take a carriage ride first thing as I heard they will not run when it is very hot in the middle of the day (I wouldn't want to either) plus that will help us get our bearings. As far as sightseeing, I think it will have to be limited to the downtown and Battery area. Anyone have any ideas for things we should not miss seeing? Ideas for shopping would be appreciated to (I am looking for things unique to the Charleston area that aren't found in the Midwest). Is there a river walk? Thanks for any suggestions!
