Chibo Gangnamsinsa is a Hiroshima-style okonomiyaki restaurant on the second floor of an alley near Sinsa Station in Garosu-gil. Hiroshima-style okonomiyaki and yakisoba are served warm on a hot plate, with sauce, parae, and katsuobushi added to taste. Seating includes counter seats, table seats, and window seats, and orders placed on each table's tablet are cooked in the back and brought out on the hot plate. Walk-ins can face a wait, so reservations are supported through CatchTable.
