Tsuki [1410 1st Ave. (bet. 74th and 75th Sts.) 212-517-6860]
An absolute gem. I am consistently amazed by how many excellent sushi restaurants there are in New York. Like many of the other ones, Tsuki has a very modest decor, but some fantastic fish. You should really make sure to treat yourself here, and here is how you should do it: Start with the 3 Salad Appetizer, which is definitely big enough to share between two people, but also worthwhile for a hungry individual. The Lobster Salad is particularly delicious and can be ordered with just seaweed (no Hijiki) in an exquisite combination. For the main event, go for the Omakase if you've got the money, but there is also a more affordable way to taste some of the best fish available. In this case, I am referring to the Tsuki Selection, in which you get six of the chef's best cuts of fish along with the fantastic Volcano Tuna Roll. In fact, this selection is big enough that you could certainly share it with someone else, along with one other roll (perhaps Salmon Carrot Sauce?), and feel full. Finally, if you still don't feel full (or even if you do), top off your meal with the Mochi ice cream. Get chocolate and vanilla. Both are excellent and come with very sweet and tasty mountain berries. On the whole, Tsuki is a very good alternative to a place like Sushi of Gari because it is cheaper, much less crowded, and of similar quality.
