At basement level, there's a good row of restaurants, and I settled on one that serves miso katsu, pork cutlet fried with a hatchô miso sauce. It turns out I'd hit the jackpot, because that's a local dish, and because I loved it! I went back for more another evening with fellow guests, and once again when I made a stop-over at Nagoya on the way from Western Japan to Tokyo. I'm definitely eating there again if I get the chance!
