For Reciprocal Club Members

Located in the heart of Washington, DC, the Cosmos Club is a haven of refined elegance and impeccable service, where guests experience old fashioned warmth and tradition along with modern technology and amenities.

Reciprocal Club members can enjoy overnight accommodations in our luxurious, unique guest rooms of the Mansion, the newly renovated Hillyer House, or the Annex. Each overnight stay includes a full breakfast for two. Overnight parking is also available on the property.

A quick taxi or Metro ride, located just steps from the Club’s front door, connects visitors with the world-class attractions of our nation’s capital.

Dining options at the club include The Garden Dining Room for breakfast, lunch, dinner and Sunday Brunch, and The Garden Bar, which offers a light menu, afternoon tea and evening cocktails. A variety of private rooms are also available for dinners, parties, weddings, receptions, and similar events.
