As an avid everything-Japan-fan, I found the food here simply pedestrian. It could be I was prejudiced as I'm not really a fan of chain-businesses attempting to "buy in" on the Japan/sushi fad; Japanese food not made by Japanese people.
There are much better efforts in the area, such as Bento Cafe, Parkway Camden. I'm afraid I will not be going back again.
Feng Sushi specialise in a range of sushi dishes including vegetable sushi along with other Japanese dishes to eat in or take away. A delivery service is also available.
