Donkatsu Monster is a donkatsu restaurant in an alley in Banghwa-dong, near Banghwa Neighborhood Park and the National Institute of Korean Language. The menu includes cheese donkatsu, fish cutlet, and cold naengmyeon, while the tteokbokki and cream soup at the self-service bar are unlimited. Side dishes are taken from the self-service bar, and you can scoop only as much as you need. The wang donkatsu is smaller than expected.
