called Newseum Nights. It's a different theme every time. One was Rock n Roll cause they had some exhibit from the Rock-n-Roll museum. The latest one, in October, was a 60's themed one. All of them are open bar (beer and wine as well as whatever signature cocktail they've created for the event). Flying Dog sponsored the event once so all the beer was Flying Dog brand. They're pretty darn good times. I think the next one is in April, around Cherry Blossom time. Can't remember what the tickets cost but I think they're somewhere in the $35-45 range.
