Calling Nozomi just a japanese restaurant would be very far from what this place effectively is.
The food is the most important issue for every restaurant and Nozomi thicks all the boxes but, rather than being just a restaurant, Nozomi is an experience which will give you the opportunity to eat Zuma's level of food along with the great music played by the dj at the bar area.
The Nozomi salad (an amazing combination of crab and asparagus mixed with truffle oil), Chilean Seabass, Black Cod Miso are only some examples of the great food you can get in this very cool restaurant hidden amongst the shops in Beauchamp Place which has become my second home since I met all the friendly staff coordinated by the professional managers.
It's definitely worth a try and I am sure you will be back in a very short period of time.
