Start with a quick stop at The King Sejong Story, a museum about Korea’s most famed ruler located beneath his statue in the main Gwanghwamun Square. You’ll be able to learn the basics of the Korean alphabet through interactive digital exhibitions, and listen to ancient Korean music. Then make your way up the national mall to Gyeongbok Palace. The palace is too huge for most adults’ attention spans so beeline for the main throne room and the lake pavilion behind it. Luckily, there’s the children’s museum in the National Folk Museum, adjacent to the palace. Kids can learn about everyday Korean life through hands-on activities. Entrance is free but reservations are highly recommended. From there, it’s a five-minute cab ride to Tongin Market, a traditional food market that’s been open for 70 years. To revitalize the old market, they started a “lunchbox” program that’s been wildly successful: For 5,000 won you get a plastic tray and ten gold coins to spend on real food from real market vendors. A typical side dish, or banchan, like cucumber kimchi or acorn jelly will cost you one gold coin, and more substantive dishes like fried lotus and pork patties will cost you two. (Tip: avoid peak lunch hours as seating is scarce.) Here, you’ll see a dozen kinds of kimchi, fried and steamed dumplings, spicy dried squid and dried anchovies, as well as noodles, sausages and fruit. After eating, head out the back of the market and cross the street to try some sodas and floats with a traditional Korean twist at the retro-themed Ruby Sodas, which also sells retro Korean penny candies (we give the mulberry float five stars). Finish off your day with a few retro games of Tetris, PacMan or Street Fighter at the old-school Ogin Orakshil, a video game arcade open since the 1980s.
