Glad to see I won't be there at the bar alone! If you are early check the bar, if late ask for "Lorna's table". If you don't know, Crystal City underground has free weekend parking. If you metro, go up only the first escalator and turn right to enter the underground restaurant and shop area. Walk straight ahead to RiteAid and turn right. You will see King St Blues on your right before you get to the exit doors.
