The Easiest Public Restrooms to Find in Seoul

The easiest way to find a public restrooms in Seoul is to head to a subway station. Almost every station has a public restroom. I, too, frequently use subway station restrooms when I suddenly get a stomachache during my commute. However, the locations of restrooms vary from station to station, so they can sometimes be difficult to find. Also, at large stations with many transfer lines, like DDP Station, you might have to walk quite a distance to reach the restroom. Even though they are easy to find, these downsides exist.
