Do the winter holidays find you thatching the roof of an edible edifice with M&Ms and paving its walkways with gumdrops? If so, Poste Brasserie Moderne invites you to participate in its gingerbread-house contest by bringing your creation to the restaurant anytime during business hours from December 10–23; entries will be on display in the restaurant and the adjacent Hotel Monaco lobby so that visitors and guests can vote for their favorites. Prizes include free overnight stays at Kimpton Hotels and gift certificates for their restaurants, with a special category for children. Everyone who enters gets a free mug of house-made eggnog (202-783-6060).
