The first review (below) must be by a PR service (an unbelievable 10 out of 10 for food - come off it!) since this restaurant is quite basic and the food really isn't good - as so many of the reviews on other websites will confirm.
I haven't tried the sushi and apparently this is not bad and is reasonably priced. But, as many reviews also confirm, the bento boxes (which I did try) contain poor quality meat, badly seasoned. When I went, a midweek lunchtime, it was less than half-full.
Why would anyone come here when two better options are less than a minute away? (Tokyo Diner and Zipangu - both fairly basic but with better food at similar prices.
Kintaro Sushi serves very good and reasonably priced sushi.
