Hatsuhana on the 48th Street location at 17 East 48th btw Madison and 5th, is certainly a great preference for eaters of raw fish.
The advantages here are the offerings of large cuts of octopus, raw shrimp as well as the freshness and professional friendly work that goes into creating the experience for the guest. This preparation with the shrimp includes deepfried head of shrimp, for those seasoned eaters of Japanese food, I am certain you know of this.
On visit not too long ago I was very pleased, and natto with raw quail egg was able to be ordered and eaten between the raw fish. I had ordered this some weeks ago at another restaurant, and was told that they could not use raw egg, because sickness may result. This fear is culturally based, in my opinion.
I recommend going early, for the dining guests become greater in number later, and you might have to wait.
