Seoul
South Korea
The convenience stores never close and neither does the city. At 2am in Hongdae, university students eat tteokbokki from paper cups under neon signs while a busker covers a K-pop song badly and everyone sings along anyway. Seoul is 10 million people living at full speed — ancient palaces wedged between glass towers, street food alleys running under elevated highways, and a subway system that makes every other city's look embarrassing.
