It's Habitat Restaurant Week. Through Friday, participating Washington-area restaurants are donating a percentage of a night's proceeds to the Montgomery County chapter of Habitat for Humanity, a nonprofit that builds simple, affordable housing for low-income families. Diners must print out tickets online, then bring them to the restaurant of their choice in order to support Habitat.

Participating restaurants include California Pizza Kitchen, Union Jack's, Potomac Pizza, Cosi and Chili's, among others. Visit to print out tickets and see the schedule of participating restaurants. - Liz Essley
