About
Katsu Ryu, located between Seongsu-dong and Ttukseom, is a specialist restaurant serving only tonkatsu, offered by cut: hire (tenderloin), rosu (pork loin), and toku-rosu (premium loin), a cut of which only a small amount comes from each loin. Katsu Ryu uses a low-temperature method, cooking the pork slowly in oil at a low temperature, and adjusts the oil temperature and cooking time to the cut and thickness.
Katsu Ryu builds on meat trimming, aging and the condition of the batter, aiming for a light, crisp crust and a moist interior. The 'Ryu (流)' in the Katsu Ryu name expresses the idea of making tonkatsu in the restaurant's own way and flow.
