This is a sister store of "osaka tonkatsu (formerly katsudon chiyomatsu)," which has been the talk of the media as "japan's thickest katsudon." the signature item at this store is the "katsu sandwich," a 5cm-wide thick pork cutlet sandwiched between fluffy toast. in addition to the impressive visuals that are perfect for social media, they are also particular about the softness and juiciness of the cutlet, as well as the flavor of the sauce that goes with it. only 100 servings are available per day, so be sure to get yours early.
