5 /5 Shifali Mudumba: Located in Japan House, this is a hidden gem of a Japanese restaurant in London. Often, you can easily spend over a 100 pounds on Japanese in London to be left hungry and/or not experiencing the taste of fresh and true sushi-grade fish. Akira is an exception to this - high quality ingredients, excellent sushi and sashimi (although dont expect unusual fish...) and a very well price for value omakase menu. Also worth calling out is the oasis-like ambience away from the hustle and bustle of High Street Kensington. Service was mostly earnest but clumsy (alcohol spilled on to the table, water service could be more attentive, multiple requests for the wine menu)...However, all in all, this was great and we will be back.
