I went tonight and I'm glad I went, and I would say this place is in the top tier. Its very different in style than Ichimura and 15 East. The rice is slightly sharper and slightly less sweet than 15 East or Yasuda. I prefer the rice at 15 East.
Live scallops that were still quivering was excellent and loved his Ikura, more soy and konbu flavor than most places. I could have sworn he switched up two different temps for the rice for various fish preps. Santa Barbara uni was served, but I prefer Hokkaido uni. The tamago was good but not my type of tamago, it was very sweet and dense like an egg custard. I prefer the castella or dashimaki style tamagos.
For Silverjay regarding the mustard on tuna, he told us Wagarashi, so I asked him, and he said "Karashi janai Wagarashi desu", not sure if he was joking or there was an actual difference between Karashi and Wagarashi. It was very subtle, not in your face. It was hard to chit chat with Nakazawa san or ask him questions because the place was jam packed, and he was swamped.
I noticed the dining room opened up, and people sitting in the dining room were served 3 pieces at a time from the counter. And I did see a solo diner.
