The building itself dates from 1600 and has a sober decor with an old Belgian bar and folding tables against the wall for when it gets busy. The clientele are mostly thirty-somethings, many who live nearby or work in the Jordaan neighbourhood. Sitting on the terrace you can watch the world go by: from yuppies in a hurry racing along on their bikes to giant herons who flap down hoping for a bite to eat.
