Fantastic and authentic Japanese restaurant on the Bund. It's on the second floor of #6 Bund, in a great Japanese-inspired space (well, except the shark tank behind the reception desk).
There are a few staff who speak Japanese, but not so much English. Definitely make reservations in advance for weeknight.
They have a pretty good drink menu, with sake, shochu (and even sours), and several flights of sake for very reasonable price. Wine was good too I think.
We started with a maguro and other sashimi moriawase, a fantastic salmon salad, and chawanmushi. Shishamo was just ok. My co-workers liked the gindara saikyoyaki (fish) so much that we got a second order of it! Yakitori was quite good too. The spare ribs melt in your mouth and flavorful.
I liked the black sesame ice cream and fried mochi dessert.
