Handicapped Accessible, Except...
I have no idea how people in wheelchairs survive in Germany. Roughly 99% of all restaurant & bar bathrooms are downstairs, in a sort of septic basement. No elevator, just a tight, winding staircase. So, if you're in a wheelchair, bring a cup.
Of course, having these steep stairs in a bar begs the question, "how do drunk Germans piss?" The men go outside & use a wall or corner. The women? Further investigation is needed...
