We're going to Charleston to celebrate our anniv next month. Looking for suggestions for a nice restaurant for dinner with great seafood with a southern flair. My husband's not planning to bring a jacket or a tie, so can't be too formal. We'll be staying in historic district, so it would be great to be able to walk, altho we will have a car. Willing to pay, although not totally over the top ( thinking around $100). Also, how far in advance do we need to make the reservation? If we need more than a couple of days I'll have to make reserv before we leave home. Suggestions would be greatly appreciated. Thanks!
