Yechon, 4121 Hummer Road, Annandale, VA, 703-914-4646, just off 236, always open, 24 hours (Metro Trip Planner - opens in new window) [Washingtonian | WaPo | City Paper | food-plan | openlist]
One of the best and most versatile Korean places, plus it has a festive atmosphere. The grilled deluxe specials are excellent but everything is consistent. The only drawback - many of the major dishes have to be ordered by both people. They have sushi too, though not early in the morning for breakfast.
