Sushi Seki [1143 First Ave. (bet. 62nd and 63rd Sts.) 212-371-0238]
Absolutely outstanding. The most unique and delicious sushi I have had in New York. I highly recommend Seki's Original Special Recipe Platter. It may be a little more expensive, but it is worth every penny for the creative combinations of fish and sauces. For those not inclined toward sushi, the Beef Negimaki is tender and tasty, and you can't go wrong with the Chilean Sea Bass. But I would still insist that sushi has to be the ticket to a splendid meal. Seki is only open for dinner, beginning at 5:30 PM, and due to the small space, you must make a reservation ahead of time if you want to eat dinner any time from about 7:00 to 9:30 PM. After that, tables and the sushi bar are often available, and amazingly the restaurant is open most nights until 3:00 AM.
