Review excerpt: Fujimaru is part of an expanding Osaka-based group of wine shops and delis, which includes the only winery in that city — and it’s their own wines on draft here. The chain has made a bold choice of location in Tokyo: The restaurant looks out over the waterfront on the final stretch of the Kanda River before it empties into the mighty Sumida. From the window, you can watch the lights of the traditional yakatabune (pleasure boats) as they set out and return to their moorings. Atmospheric rather than romantic, but with an undoubted charm, this riverine setting is ripe for discovery. A stop-off at Fujimaru makes the journey worthwhile.
