Went for lunch, and just wanted to say that most of the things people have mentioned for dinner are available on the lunch menu as well.
Notable exception: chawan mushi with lobster and uni. I was very disappointed not to see this on the lunch menu, but our waiter was very sweet and asked the kitchen if they could do one anyway. He said they're happy to do it if you call ahead and say you want a chawan mushi at lunch, but that if you don't call ahead the dish might lag. As it turns out, it didn't lag at all today and came out as hot, fragrant, silky, and wonderful as everyone has said. Mixed into the custart were lotus root slices, shitake mushrooms, lobster chunks, and thinly sliced okra One regret: we got a Maine lobster claw instead of the tail. Maybe the tails are reserved for the dinner chawan mushi?
Poke: delightfully crunchy, almost invisible tempura batter with three kinds of fish chopped up in the filling. Tuna, local halibut, and one that I forget.
Ceviche: I was admittedly unexcited about this choice, but I don't regret it at all. The mackerel ceviche came rolled up in paper thin slices of daikon pickled to a bright pink. Lovely combination of flavors--slightly tangy daikon with that gamey mackerel. Fish here is fresh--I usually like my mackerel cooked and I couldn't get enough of this. My friend said it reminded him of the ceviche he had as a kid in Lima.
Alaskan Cod: mmm, miso glaze. Enough said.
Miyagi oysters in lettuce cups: it was almost a waste of the oysters to cook them like this, but I can't imagine an oyster lettuce cup tasting any better. The batter was light and crispy, the oysters were still raw in the center, and the lettuce was butterleaf.
I do regret not getting the tuna crudo. Saw some at the next table and the color was a fantastic color. In Ame's black/brown dining room, the blood red of the tuna stood out like the little red cape of that girl in Schindler's List.
3 sorbets: strawberry, rhubarb, and mango. Good, but not phenomenal. Many San Francisco restaurant churn out better frozen treats (Zuni, Sketch, hats off to you).
