Delicatessen Shinjuku Saboten Sengawa Keio Store

This takeout-only tonkatsu shop is directly connected to Sengawa Station, located within the Keio Store. The freshly fried coating is light and not greasy, enhancing the flavor of the meat, and you can enjoy two different tastes with the special sauce and grated ponzu. In addition to the classic tonkatsu bento, there is a wide variety of options including fried oysters and rolled tonkatsu, and despite being a chain, it is well-regarded for its consistently high quality.
