Our respected gourmet colleague took us to another new restaurant in an old neighborhood. Called Yama-Shokudou, meaning "mountain diner" in English, if you must translate.
A dimly lit, very low-key Japanese style restaurant. They have traditional home cooking menu with fresh vegetable and eggs and such. Everything we had was so delicious. This Japanese wine, below, was also one of the best I'd had among Japanese ones.
This area seems to be becoming more hip in the recent years. Something like below, an eclectic second-hand book store, is also nearby.
