Kwang took me to the seafood market in Seoul a couple of weekends ago. It was amazing. I have never seen so much fresh seafood. The size, shapes and abundance of seafood was truly impressive. Most of the seafood caught in the waters of Korea is transported to this market. You can have sashimi of many forms right on the market floor. There are also restaurants that are BYOS(seafood) and they will prepare your catch of the day.
