Gatsuhyeon is a restaurant in Seoul's Songpa District that serves only Japanese-style handmade pork cutlets. It offers rosu katsu, cheese katsu, and naeng momil, and the cheese katsu is made with pork loin and cheese and has a soft fried coating. At lunch there is a line, and diners mix the sauce themselves from sesame powder, teriyaki, and mustard. The shop is small, so it can feel cramped during meal times.
