Noryangjin Fish Market is Seoul’s largest and oldest indoor market, and a must-see for any visitor. In the main hall, you’ll find the day’s fresh catch (baby squid in summer, kalchi (silver belt fish) in fall, clams in winter, and ggot-gae (a favorite local crab) in the spring. Mornings are generally when the real wholesale action happens, but casual visitors looking for a meal should head over in the early evening. Bear in mind: close-toed shoes that you don’t mind getting wet are an essential. Once you’ve made your purchase, the seller will direct you to a restaurant along the edges of the market where you can enjoy your seafood raw (hwae, in Korean, though international visitors may be more familiar with the Japanese term “sashimi”). If raw is not your thing, you can have your fish grilled with sea salt (gui) or have your octopus steamed (jjim) with a side of red pepper dipping sauce. Once you’ve finish your first course, have your remaining fish bits made into maeuntang, a very spicy and flavorful stew. When it’s time to walk off lunch, take subway Line 1 up to Jonggak Station (exit 5) and stroll along the Cheonggyecheon, a lovely urban stream lined with greenery that’s often compared to New York’s High Line.
