Normally, I'm not a big fan of chain restaurants. And, actually, I don't eat seafood either. I recently went to Charleston with a large group, however, and we dined here. We made arrangements in advance to visit as a group and they really did a spectacular job of it. They emailed us the group menu in advance, giving adequate time to plan for different people's dietary needs. When we arrived, they had us arranged at several tables close to each other - not one giant rammed together table - which was much more conducive to conversation. Each place had a menu that was personalized to welcome our group. The group package contained one appetizer per four people, a salad and dessert for each person, and a choice of entrees (there were six or so to choose from, both seafood and non-seafood). During the evening, a server ran a trivia game based on "Forrest Gump", handing out prizes to the group. I'd definately visit again, especially if I needed a place to feed a group!
Note: don't pass up the opportunity to race the rubber ducks on the patio out front!
