I had meals at YU last month - for some reason, it wasn't as extraordinary as I remembered it the first time. We had booked a table at SPOON, but canceled it as soon as my friend discovered the menu is not that much different with the one in London and Paris. I personally find the mix and match thingy a bit silly.
The best meal I had last month was at the IC's Chinese Restaurant (forgot the name). We should've gone there for Peking Duck as well. The one we got sent to (by the Ferry building) is mediocre, to say the least. The Peking Duck restaurant in NYC is much better than that one.
In my opinion, hot tables do not necessarily mean great food.
