I recently went to Kiku on Half Moon Street, Mayfair for my wedding anniversary. Simple but stylish wooden surroundings and an almost entirely Japanese clientele (apart from a boy and his mother who were regulars). We had the Edo kaiseki for £60 a head. Admittedly the sushi course wasn't the best I've ever had, but the rest of the courses were amazing - and it was all beautifully presented (proper food porn). I'd definitely go again in a heartbeat - or take anyone I needed to impress. These were the appetisers: The rest of the photos are here if you're interested.
