Sinseong is an old Japanese restaurant near Cheonggyecheon in Jongno-gu, Seoul, serving aged hoe and barley gulbi. The menu includes thick slices of aged hoe, a barley gulbi set meal, and hairtail kimchi. At lunch, customers come for barley gulbi, hoe-deopbap, and seodeori-tang, while in the evening they order hoe and drinks, and reservations are required. The facilities and interior are old, so a luxurious atmosphere is not to be expected.
