My wife and I have been trying a variety of sushi restaurants in London. We recently ate at Miso Sushi based on the recommendation of a co-worker. It proved to be an great reco!
We ordered the sushi/sashimi combo for 2. Nice presentation, very fresh fish and nearly the right amount of rice. The chef knew what he was doing and is highly experienced. It turns out the he previously operated one of London's oldest and most prominent sushi restaurants, before selling it last year and opening Miso. As a result, Miso is an excellent value and well worth a visit.
It will give the other Richmond Row sushi restaurants a run for their money!
