I have heard good things about Tonki, a tonkatsu (deep fried pork cutlet) restaurant in Meguro. I guess I thought I had seen it all living near another legendary tonkatsu shop, Maisen, when I lived in Harajuku. But I decided to check it out since it is at the next station over from Ebisu, Meguro, and it was sublime. They only do two types of tonkatsu: rōsu (fatty pork) or hire (lean).
I went with the hire (lean) teishokua (dinner set with oshinko (pickles), miso soup, and rice. recommended.
