If you haven't visited Asia's mighty hub of pop culture, it's high time you did. Beyond the billboard teenyboppers and glass towers of Gangnam, Seoul has a vibrant underbelly of ultra-cool that much of the world is just beginning to discover. Far more than just chic cafes and Korean craft brews, the city is home to graffiti a covered basement bars and hidden restaurants serving both traditional and fusion cuisines.With the 2018 Winter Olympics looming, now is the time to experience Korea's capital before the crowds take over. Seoul is one of the world's great 24 hour cities and a veritable assault on the senses. Martin Zatko, author of the Rough Guide to seoul.
