The two craziest things that I ate in South Korea would have to be live octopus and dog. For live octopus they bring an octopus out, knock it out, then cut off the tentecles and serve them on a plate. You dip them in hot sauce and eat them while they are still moving. And dog is well, dog lol. They breed a special kind of dog and many restaurants don't even serve it. I do have to say it tastes like chicken haha.
