There is some delicious seafood to be had along the coast of Korea. Last summer I enjoyed this raw feast with friends at a restaurant in Gangneung, Gangwon-do. We sat outside and stuffed our bellies as the sun set over the ocean.
Fish and shellfish are popular throughout Korea and you can see seafood restaurants all over Seoul, with tanks full of live dinner outside. But I recommend a trip to the seaside for the best experience.
