For the month of October, Pink Jams! has a great DC-area event going on where people can eat great food and help out a great cause!
Here's the background information from their site:
Take a Bite out of Breast Cancer is an outreach and fundraising campaign focusing on educating Washington, DC area residents about the importance of early detection and awareness, and supports Pink Jams!, a DC area non-profit promoting breast cancer awareness to young men and women. By combining this important message with fashion, art, social events, and live music, Pink Jams! is reaching out to men and women under the age of 40.
For the entire month of October, chefs and restaurateurs will commit their establishments for one day, a week, or the entire month, and generously donate a portion of their food and beverage sales so that Pink Jams! can continue their work to save lives.
