Despite the name, this is a relatively quiet area that doesn't have a downtown feel but is near the hospital. This place offers some niche and local goods for sale and does have freshly prepared beverages. Freshly prepared food for lunch was in the offing as well, but apparently not for breakfast when I stopped in. I got a chai, which no one could accuse of anything other than being strongly, flavored both in terms of being very sweet, but also substantively with the other aspects of the chai. I picked up some local potato chips as well.
Charleston has no shortages of places like this that offer niche and high-quality food. This one would be a nice place for a lunch stop.
