Hi, I am Japanese who lived in Osaka and Tokyo before coming to London.
In recent years, there are many restaurants in London, called Japanese restaurant. However, it is not real Japanese one and taste is completely different.
Since I would love you to enjoy real Japanese taste, I recommend 5 real fantastic Japanese restaurants to you.
Eat Tokyo is a Japanese Izaka-ya style restaurant. Sushi is really fresh and dedicated. Taste is much similar to Tsukiji which is a famous place for largest fish market. Moreover, Eat Tokyo offers Bento-style food (Fried Chicken Bento, Unagi-don(Eel bowl), Chicken-Katsu Bento, etc) which is like a Japanese common lunch. Price is much reasonable. You should be first choice when you look around Japanese restaurant.
