Had the 7-course dinner at Masaki recently and thought it was one of the most satisfying high-end meals I've had in Chicago in a long time. The service was great and the room is one of my new favorites in town. (The better half of the Pelago-Masaki team is a tremendously talented designer, in my view at least.) While the 7-course (all fish, all raw, pretty much) menu had one or 2 duds, an insipid monkfish nage for starters and rubbery tako, they were few and vastly outweighed by the quality of the produce and the presentation. Some Chicago (maybe US) high-water marks for me included the otoro and the uni. Also, important to me, the shoyu. I have seen some criticism of the rice, but there was virtually no rice in this meal, even under the few nigiri, where the rice ball tended to be very small in comparison to the fish. I would like to think a Japanese fish restaurant of this caliber is capable of producing outstanding rice, but I can't say for sure. A loose porridge of glutinous rice with shrimp innards was terrific, though.
Nice attention to detail - even the mignardises were great and cuisine-appropriate, mimicing the custardy, Portuguese sorts of things on hand in the Mitsuwa bakery. Others nearby had cooked foods from the other menus and it all looked swell. The wine list seemed interesting and appropriate, with lots of dry cold stuff, plus a large sake list. I drank beer and sochu, though. Not cheap, and lacking the kind of freedom of creativity of true omakases with its fixed menus, I still think Masaki is accomplishing what it sets out to do, admirably and early in its life. After flings with mirages like Matsumoto and Heat, or even steady performers like Katsu, Arami and Mizu (Matsumoto's current digs), Masaki stands out as a very serious, high end vision of "real" Japanese food. I liked it.
Looking now, I see that the only real pro review so far is from Sula who conveys a similar vibe about the place, I think.
