What are some amazing and weird Korean foods I should try?

The best thing you could possibly eat in Korea is all the sea food they eat, and dog soup.... no, I'm serious. Many things like this may be weird to you at first, but the worst thing you can do is clam up and become xenophobic (like the people who give thumbs down at the idea of dog soup). I don't recommend the silk worms you see cooking at all the food stands in the winter, but you may like it, haha. If you are into weird food, just try everything you see. Korea does have some excellent food!
