My favorite roast duck restaurant in Beijing, Liqun, is a bit tricky to find if you’re a first-time visitor. It’s located in a hutong, or alleyway, and the neighborhood isn’t particularly well-lit at night.

Fortunately, someone came up with the ingenious idea of drawing a series of ducks on the side of a building nearby. So once you get close, all you have do is — literally — “follow the ducks” … and then eat them, of course.
