We had a company dinner at Shinbay in 3 weeks ago. 4 of us had the 5 course meal, $80 each, excluding drinks. Other reviewers have described the menu, so I will not go into details.
My thought was the food was good (not high) quality, beautifully presented and well tasted. However, I thought it was overpriced for the amount and type of food they served. The clams with mushroom, seafood bites, etc didn't worth the price. Although the quality of the sushi fish was good, they were too thinly sliced. I am not a big eater, yet it was not enough to fill my stomach in that evening. All of us walked out feeling half full. My Japanese co-worker thought the meal was worth about $50.
I travel quite often for my job, and I can find higher quality seafood (such as otoro) in both Japan and US at a more reasonable price.
