"Do you know the mountain halls on Unter den Linden? You ought to
pay them a visit some day. The entrance fee is just thirty cents. Even
if you should happen to see the cashier eating bread or sausage, there's
no need to turn back in disgust, just consider that it's her supper
she's eating. Nature demands its rights everywhere. Anywhere there's
nature, there's meaning. And now you'll step inside, into the
mountains."
Robert Walser, "Mountain Halls".
