Tonkatsu on its own is a great dish, as is curry, but combined as katsu curry is a great way to hit two sweet spots in one dish. Ouroji 王ろじ is a tonkatsu shop on a quiet back street near Shinjuku Isetan. Katsu curry here is served in a bowl and is called tondon (tonkatsu donburi). The rice is from Niigata and is the right texture and slightly sweet. The curry is not at all spicy, and in the Japanese-style, so if you like heat, look elsewhere. The tonkatsu is a thick piece with a crispy coating that is dressed with some sweet sauce over the curry. Ouroji opened in 1921 and it has an old school feel to it.
