A Vrai French Bistro in London or environs

[75 percent cacao]

I'll be in London for a week, from 24.xi.08.

As I used to live in Paris, I know that the chunnel has made cross-fertilization of all kinds of seeds possible.

So:

Where are those disaffected French restaurateurs who moved to London and opened bistros?

I'm not one for atmosphere, reputation, or who needs to have lots of people around to attest to the authenticity of the (French) cooking.

Any recommendations?

Thanks in advance for your help.
