Ieung Gacheu in Charosugil, Seoul is a tonkatsu restaurant that serves hire, rosu, cheese, and fried shrimp together. The hire and rosu are eaten dipped in salt, with tonkatsu sauce on the side. There are seats for solo diners, and the restaurant can have a wait when visitors crowd in. The cheese tonkatsu stretches into long strings of cheese, which makes it awkward to eat.
