I can't speak for *A Flyer, but having organized a DC Do several years ago (and being involved with the DC Happy Hour group for a long time), I can tell you it is really hard finding venues willing and able to handle large groups, particularly where you don't know exactly how many people will show up until the day. I'm guessing there will be plenty of venues offering Prussian cuisine that we can visit for lunch between the tours *A Flyer has arranged.
