I've dined at Nobu in Tribeca many times. Most recently, I met a friend for lunch there around 12:30pm. We made reservations, which are necessary at that time. The crowd is a mix of business lunchers and tourists.
If you haven't eaten at Nobu before, it's a good idea to have the waiter introduce you to the menu. The portion sizes will be key as you order. We shared the yellowtail tartar with caviar in a wasabi sauce. It was beautifully done and just on the cusp of too spicy. That was priced around $15.
For our main course, I ordered the lunch special of a selection of sushi and one roll. It also came with a small salad with ginger dressing and miso soup. They do not bring spoons with the miso soup, as you are supposed to sip it out of the bowl. You can use your chopsticks to eat the tofu from the bowl. The sushi was wonderfully fresh. The yellowtail had the smoothest texture. All of it was flavorful. That special was around $20.
My friend ordered the lunch special as well, but got the salmon in pepper sauce and vegetable tempura. The tempura was perfectly light. It was a full salmon filet (I estimate 6 ounces) with a subtly flavored, creamy pepper sauce. The salmon was excellent, although not really exciting.
For dessert, we shared the bento box. It comes with a small chocolate souffle and green tea ice cream. The price is $8. The desserts are beautifully presented and are worth the price.
Although the food is excellent, the service is a few steps behind. You would expect them to be really on top of the service, but we found ourselves repeatedly asking for things we ordered. Eventually, they did bring everything, but we were a bit annoyed, especially given the prices.
We left Nobu feeling full and satisfied, but not weighed down with heavy food.
Based on other trips to Nobu, I'd recommend the yellowtail with jalapeno for a nice amount of spice. I also really enjoy the black cod with miso sauce. It is one of their signature dishes. The texture of the fish is unbelievable!
I think it's definitely worth the trip. You can spend as much as you have in your wallet on dinner at Nobu.
