Welche Art von Essen probieren diese Streamer in Korea?

They’re eating nakji, which is Korean small octopus. It’s often served spicy (nakji-bokkeum) or sometimes very fresh with sesame oil. A lot of people outside Korea recognize it from the movie Oldboy, where the actor famously eats a whole live octopus. It’s a pretty common dish in Korea, especially at night markets and street tents (pojangmacha)

It’s sliced raw octopus.
