I'm sure many of you understand the perils and horrors of public restrooms: whether in New York or Beijing, finding a reasonably sanitary, let alone pleasant location to relieve oneself can seem next to impossible.
Thus, I present to you Reason #2 To Love Seoul:
Public restroom (hwajangsil), labeled clearly in Korean, English, and Chinese
A typical Seoul subway station restroom:
clean and well-lit, with self-flushing toilets and urinals, a baby changing station,
and security buttons for those requiring assistance, cf. New York City
(I would take more pictures of public restrooms in Korea,
but I got enough strange looks taking this one.)
