Hannam-dong is like the Beverly Hills of Seoul, where the rich and famous come to play (and live). It's got all the fancy restaurants, high-end shopping centers, and luxurious apartments you could ask for. And, of course, it's also got a bunch of die-hard BTS fans lingering around, hoping to catch a glimpse of their favorite idols (no judgment, though - we've all been there).
But, what's really cool about Hannam-dong is that it's got a lot of historic significance, too. It's where the US military base used to be, and now it's all fancy-schmancy with art galleries and upscale cafes. So, if you ever find yourself in Seoul, make sure to check it out (just don't stalk the BTS members, okay?).
