The venerable George Town Club, known for members involved in business, politics and diplomacy, invited hundreds of the younger set of Georgetown to jazz up its menus, decor and programs Feb. 1. “Come Celebrate The George Town Club . . . and see everything this gem has to offer,” read the invitation that drew in the 20-, 30- and 40-something crowd in hopes of getting a rejuvenating rush of fresher ideas and new members. The historic dinner club, founded in 1966, boasts a site at Wisconsin Avenue and Volta Place with links back to George Washington, Pierre L’Enfant and the founding of Washington, D.C.
