A carriage tour through downtown Charleston is a great way to spend a couple of hours. Done it many times. As far as dinner/brunch is concerned, High Cotton is my place to go.
On Sunday morning, they have a jazz combo playing in the bar.
Best espresso martini I've had.
Enjoy your time in Charleston, it's a great city. <img src="http://www.traveltalkonline.com/forums/images/graemlins/toast.gif" alt="" />
