Well this is insane/hilarious. A chain Izakaya connected to fish farms in Japan on lex and 36th is selling whole fish from Tsukiji from a small iced case at the front of their bar. A kinmedai was $200 and he was kind of open to selling me a "display" huge red snapper that the thought was a day too old for $50 that looked much much nicer than anything else you would see around town. I ended up buying a bunch of Nodoguro/Black throated Sea perch for 20/per that were wonderful.
I mean this won't last and I'm not sure it should, but its def worth an entertaining check in if you are in the nabe.
(they don't really know what they want to do or what they need to do to sell this fish to americans - like they were asking me how I was planning on butchering the red snapper, and when I didn't have a good answer beyond "Uh I might filet it?" it was clear to me they wanted to sell the me Nodoguro which had already been prepared for the grill)
