Our catering staff can assist you with special functions of almost any kind, from a quiet dinner for six in the National Geographic Room to a special wedding anniversary celebration for 200 in the Warne Ballroom.

Functions can be for yourself, for a member of your family, or you can sponsor events for a friend or associate.

The Club specializes in various types of events that include meetings, receptions, and sit-down dinners.

Custom centerpieces, fresh flowers, and fine linen and china are just a few of the elegant touches from which to choose. Exquisite food and beverage selections provide a choice of traditional or contemporary fare, all prepared with the finest and freshest ingredients.

The elegance of the Townsend Mansion graces each and every room. Designed and constructed by Curtis John Hillyer in 1873, the Cosmos Club is a historic downtown landmark. The Club’s beauty and ambiance creates a setting that is impossible to duplicate in more modern facilities.

The setting for your meeting will be filled with old fashioned warmth and tradition along with all of the modern technology and amenities of the 21st Century. Our staff can supply any group with state-of-the-art technological audio/visual equipment from LCD projectors and DVD players to cordless microphones and amplified lecterns.

Entertainment to match the mood of your event requires established connections with area musicians. Whether you would like a string quartet or a piano player, background music or ballroom boogie, our staff has extensive experience and excellent relationships with our area’s top entertainers.

Call us at 202-387-7783 to discuss setting up your special function.
