Seoul's Sewoon Cheonggye Shopping Center is an old electronics market in the Cheonggyecheon area where you can find electronics and arcade game machines. At Ppau on the third floor of the Daerim Building's Ra row, simple food centered on donuts is served. The second-floor shopping area is active, and the ninth floor has a rooftop space. Shops close early, so a visit before 6 p.m. is necessary.
