Who doesn't want to eat at Nobu at least once? When you step into the restaurant, you'll forget to walk for a second because it's so beautiful. There are so many interesting structural elements in one space, whether it be the light fixtures hanging from the top of the ceiling, or the semi-enclosed pods along the edge of the restaurant.
Nobu is all about the experience really. With a variety of items on the menu, I highly recommend going in a big group, everyone getting some things and sharing items. It's an experience of many senses: sight, smell and taste. If you came to Nobu to dine on a budget, don't. The bill won't be cheap, but you will be full. You're not coming here every day, so if you come, be prepared to splurge.
