Yes, I’m not one to actively choose a truffle slice (or gold leaf – although I do occasionally garnish Indian sweets I’ve made at home with silver leaf). I went for the “platinum” option over the base because I was promised more interesting fish. (The owner, Youji Iwakura, is very obliging and very responsive on email.) If you look at the list that @Parsnipity posted of the fish in the basic choice – at that time – at the top of this thread, the OP, you’ll see that I did indeed get a somewhat more interesting selection. But, at this price point I certainly can’t do it more than once more in the near future.
@Parsnipity’s list is of their sushi (Fridays are sushi and Saturdays chirashi). Interestingly the fish list that came with my box is structured like a menu for an omakase. Each item is presented as a composed dish: Uni with marinated ikura, scallop with bottarga, toro and truffle, etc. There’s possibly also an intended eating progression in the order in which the fish are listed, with scorpion fish with yuzu flavored roe at the start, and toro at the end. But, when things are mashed together in a small tray, it’s hard to keep the tastes separate, and roe toppings tend to slide off.
At 6 o’clock and at the center in my picture there’s a bunch of delicately cut herbs and lightly pickled vegetables – they were all excellent, although I too late discovered paper-thin rings of habanero at the bottom of the pile.
