Kiraku - Ealing Common London (WOW)

Been here about 5 times now and this no frill place, full with Japanese people has some really good stuff.
Traditional dishes and had some fantastic torro.
Not a romantic place but food is so good. This little restaurant was voted as best Sushi restaurant in London over several years.

Cocoon - London Regent Street

Absolutely original atmosphere, very different, clubby. lounchy...
Sushi is so so. But this is really an original place and great to take out business partners or hang out with trendy friends.

Zuma - Food like Nobu and Roka in a much nicer environment

Beautiful people, beautiful place, beautiful food.
Contemporary Japanese.
Got invited twice to this restaurant and the place is truly something special.
We ordered a lot of different dishes and everything was beautifully presented and tasted superb.
It has the same feel as Nobu and Roka but I find the atmosphere more relaxed and thank goodness not so noisy.
Price superb as well probably....
