Just learned that Dogfish Head Alehouse, in Falls Church has started trivia on Wednesdays at 8 PM.
I just called the restaurant for more details. The quiz is operated by Team Trivia, in the same format as we have played at other places. For those unfamiliar, they ask a question and then play a song (3-4 minutes, like what would be played on the radio), within which to turn in the answer.
Trivia is hosted in the cocktail area, and that area does get crowded, so I'll make a reservation a few days before the event (they said they would do their best to accommodate). I'll post a comment on how to find me when I get to the restaurant.
There is parking at the restaurant. For those taking public transportation, the 28A and 28X buses from the West Falls Church metro station will take you to within reasonable walking distance of the restaurant.
