I'm not sure what to make of this place.
On the one hand, the taste of the sushi was probably the best that I have had in New York. Every flavor was perfectly balanced, as were the textures. Each of the three members of our group had the tasting menu, and every course was artwork, both beautiful to look at and to experience. I would also add that not only was each piece of fish interesting, the restaurant made an effort to get some interesting local greens to include, and let us know the origin of all of the fine ingredients.
On the other hand, the portions were miniscule, and I'm not a big eater. I usually find restaurant portions, even at high-end restaurants, far too large, but Jewel Bako goes way too far in the other direction. I was hungry at the end of the meal. The service also left a great deal to be desired. It was fine at the beginning, but towards the end, it was very apparent who the regulars were. We were ignored, and there was a remark by the owner(?) to a member of our party that was very rude.
So, I'm wondering whether to go back again. That sushi is extraordinary, not even comparable to your average sushi place, almost enough to make the lack of food and decent service worthwhile.
