More about Brainfood:
Brainfood is a non-profit youth development organization based in Washington, DC. Brainfood has been a community presence in the Columbia Heights neighborhood for several years, and in the fall of 2006, a second Brainfood site was established in Chinatown. The Brainfood kitchen is a place where young people come to have creative, constructive fun. We believe that supervised, fun activities are a young person's right, not a privilege, and we have found that most of our students do not have access to such opportunities.
