The Alfalfa Club is a social club that exists only to hold an annual black tie banquet on the last Saturday of January at the Capital Hilton in Washington D.C., with an after-party at a local restaurant. The banquet, which lasts 4 hours, features music by the United States Marine Band as well as a political roast. There are approximately 200 members of the club, all of them influential politicians and business executives. The club has an invitation system; members are required to be invited to join. Invitations are extended to prospective members annually to fill the spots of recently deceased members. Several Presidents of the United States have been members of the club. The press is not allowed to attend the banquet.
