Pretty sure this is just Nobu's famous recipe, no?  Any distinction?  The Miso Black Cod is, I believe, Nobu's best-known dish, and I've seen it imitated at a lot of different sushi-type places around New York.  It's an astonishingly simple plate. 

Matt... you sound pretty smug... apparently a chef?  a food critic?  or just Critical?    The dish sounds delish... I don't care who makes it, what it is called or where it originated from.unless of course Voltaggio Brothers invented it, then it very Important  :)
