I went there 8 days after opening, really solid food for the most part! Our waiter was amazing (sans his very bad breath), can't remember his name, the bussers were kind of clunky and awkward but I'm sure they've gotten better.
They have some really special japanese items including some of the better Japanese Single Malt Whiskies, some great Hitachino Beers (including their sweet stout), an option to have REAL grated wasabi not the green horseradish paste, and the higher grades of including Chu Toro and Oh Toro Tuna Belly (Toro)
We were a table of 5 shared a ton of different things including, Bao Style Pork Buns, Dim Sum Spare Ribs, Dumplings, Peking Duck, Calamari, Yard/Long Beans, Whole Fried Fish, and sushi rolls and had their churros for dessert. I had Chu and Oh Toro (Fatty Tuna Belly), one piece each, $8 and $12 respectively. I can conclusively say that I'd easily spend $12 on another single piece of Oh Toro, it was that good.
From what I remember:
Bao style pork buns were great but larger inside than expected we couldn't finish all 4
Spare Ribs were excellent but sweet
Dim Sum were great
Dumplings were forgettable
Calamari was forgettable
Peking Duck was very good but wouldn't be if you're animal fat adverse as the thick fatty skin is still on the slices of breast meat
Fried fish was great but very sweet as well, they put the veggies and sauce on top of the mid section of the fish and that made that whole section go from crispy to soggy really quick
Yard/Long Beans were a great side
Sushi rolls were basic we wouldn't order them again, I was expecting more "special" rolls to be available
Churros were pretty good the boston cream and nutella (which came in a little sealed squeeze tube, think neosporin) toppings were a nice touch
Chu Toro was ok, not worth $8/piece
Oh Toro was one of the best things I had the whole trip (including some of the items on the Victoria and Albert's 10 course) I'd easily be back for a few more pieces.
As to whether it was worth it overall I definitely would go back, but idk if it'd be at the top of my list for anything other than a sparerib appetizer, a half dozen pieces of Oh Toro, some Hitachino beers and a Yamazaki 18 Yr Single Malt.
They also have a walk up window now for some appetizerey foods if you'd rather spend the
DDP credits elsewhere but still want to try some of the stuff. I want to go to both Morimoto Asia and the Morimoto Asia Street Food window on our upcoming trip
