What is a must do, must see, in Charleston South Carolina?

Bowens Island Restaurant on Folly Road (the main road to Folly Beach) is unique in every respect. It's a real one of a kind. You can't go to Charleston without going to Bowens Island Restaurant! You've got to hit the city market on Market Street downtown. Try the rooftop bar for a cool drink and a great view of the harbor at the 'Library' on Vendue Range, within walking distance from the market. Also try Wild Wing on Market Street for great wings. Go see the 'Angel Oak' on Johns Island. It's said to be the largest and oldest live oak tree. It's huge. While you're over there try Gilligans seafood restaurant. Good eatin'.
