Chocolate Festival at Lexington Market
We went last year and were a bit underwhelmed. It was fun to be at the market (we hadn't been there in a while), but the chocolate portion was smaller than I would have thought for a chocolate festival. We got there pretty early, though, so the entertainment was just starting up as we left. If you go into it thinking you'll spend about an hour - and you take in the sights of the rest of the market, it is a fun Baltimore adventure.
