I decided to give Nakamori another chance since I was in the area and I'm glad I did. I had a good time here this time by focusing on the basics - good fish, which this restaurant has in spades!
The chef really likes his mackerel, and I agree. Since it can be too fishy for some so it's not extremely popular and some restaurants buy prebought marinated saba or do it half-assedly. Not so here! Robust but not overpowering flavours and excellent texture on this fish. I also had a piece of succulent fatty tuna belly.
Their chirashi is beautifully presented and comes with a plethora of fish ranging from more tuna and salmon to lightly-seared scallops and two variants of shrimp. I will complain about the imitation crab, but in the future I can just tell the chef to serve me something else (it'll probably cost extra, but it's worth it!)
