IAD/LHR VS clubhouse is far and away superior to any other lounge we (wife & I) have ever been in. In addition to quality wine, they provide a meal. Read the VS posts.

On a recent AZ Mag flight at IAD, we were told to use the NW lounge, not the AF lounge, as the flight left from the KL lounge(???). KL lounge is far superior to RCC.

Sure enough, AZ flight XXX left from the back of the KL lounge. A people mover showed up, 5 people got on, and we were taken to the front door of the AZ flight.
