Sushi Zo - great fish quality, technique less so.
I'm probably one of the few detractors on this board.
Had dinner there last week, the fish quality continues to be very good, however his technique leaves much to be desired. Pinkie size rice, with barely there slices of fish that get lost in your mouth, just not a fulfilling mouthful. Fish slices are hit or miss, some are sliced too thin and torn in the middle. A lot of pre-sliced fish behind the counter. Several instances of mushy rice.
For $150 per person, there are just better options in town IMO.
I've only been to Zo 4 times, but my experience with the look of the sushi in terms of both the slicing and the rice ratio is consistent with the nice close up photos shown here in the review by Kevin in his Kevin Eats blog: http://www.kevineats.com/2009/01/sush...
I've always had the sense that the thinly sliced fish was being paired with less rice as a "philosophy" of taste and texture by chef Keizo. I've always enjoyed Zo. My experience at Mori and Zo have been very similar in terms of overall happiness with both the freshness of the fish and taste profile of each bite. Zo does tend to hit some of the sauces harder, but I also have found that enjoyable.
