London Chocolate Making

Where in London can I buy a good cheesecake?
I am looking to get a non-baked cheesecake (something like the White Chocolate and ginger cheesecake Wagamama makes) for a friend as her birthday cake. Where in London can I buy one / which bakery makes the best?
The fruit cheesecake from Patisserie Valerie is absolutely fantastic. Here’s a photo

They have branches on Soho (Old Compton St) and Kensington – maybe other areas too, check their website.
