Forget Umu, Zuma et al; nary a Japanese customer waiter or chef in sight, for good reason. Real Japanese food in London is in the 'burbs where the Japanese live. If you insist on staying central go to Cocoro. You won't be able to people-watch but you will get a very reasonable, authentic and heartfelt meal surrounded by appreciative Japanese customers and polite, knowledgeable service by Japanese waitstaff.
