One thing that most people miss when visiting the Admirals Club on the E concourse at Washington National is the VIP Room. It’s tucked right behind the checkin desk on the right as you get off the elevator.
This space is unique among clubs, built because the airport sees a large number of Members of Congress, Supreme Court justices, heads of Executive Branch agencies, as well as visiting dignitaries from abroad. You and I aren’t be invited in (usually).
