"Atari-Ya" is a chain of Japanese restaurants and shops in London supplying quality fish and Japanese food to it's customers. 
The shop is not big, but packed with all kinds of Japanese ingredients for those who loves Japanese food!
The best part for me is the fresh fish counter catering for sashimi and sushi dishes! You can order, choose which cuts you want and watch it all expertly prepared by the chef!
They offer up some of the best tuna available but our favourite has to be the salmon so we took loads, as well as some large red prawns and scallops.
Later, I cooked some sushi rice at home and made each sushi morsel myself. The fish was beautifully fresh as always and every piece of sushi and sashimi was mouth-watering delicious!
The price for this type of Japanese sashimi is never cheap, but still is a total bargain compared to what you are charged eating out at Japanese restaurants in Central London. I would say it is worth every penny, lol.
I would highly recommend the "Atari-Ya" shop for a delicious fresh fish take away. Enjoy!
