One thing I miss about Germany is Christmas, and I was too young and stupid when I lived there to appreciate it. A Weinachtsmarkt (Christmas Market) is full of the smells, sights and sounds that are the origins of worldwide Christmas traditions.
Today (Friday) until Sunday, there is a German Christmas Market at the Seongbuk Multicultural Village Center. Here’s a map. iTour Seoul has the details.
