Tonkatsu Maisen Grand Stard Tokyo is a tonkatsu restaurant inside the ticket gates of Tokyo Station in Chiyoda City. The hire tonkatsu is tender, the portion of rice is large, and the yellow sauce is mustard. The wait clears quickly, and there is space to leave a suitcase next to the kiosk. Because it is inside the ticket gates, you cannot enter directly if you look for it from outside the station.
