Seki -- which, BTW, has fast become a favorite, go-to spot -- is serving a 21-item osechi box for New Year's Eve (until midnight, I believe), that is said to be enough for two people, perhaps even more if slightly supplemented by regular menu items. $110, which is approximately one-third of the price of the osechi box at Taro (http://www.sushitaro...poster_2014.pdf) (which I'm sure will also be great, but still, $300?).
If I didn't have longstanding dinner plans, I'd definitely be there. If you go, please report back here.
