Chamchi House is a tuna restaurant in Sindang-dong, Jung-gu, Seoul, next to Exit 4 of Sindang Station. It serves tuna hoe and single-plate dishes, with tuna hoe as its main menu item. The shop moved here from inside a market, and the indoor space is kept clean with working air conditioning. A married couple runs it themselves, so staff explanations of the tuna and serving service are not to be expected.
