Recommendation for bookstore in...London

[Christer Bergström]

Is there a bookstore in London?

Sorry - I admit that I feel a bit ashamed to ask, but I am not such a frequent guest in London as I wish I were. Last time I was there, I wasn't there - it was in March, and I only went to meet a couple of pilot veterans, and really didn't see London. Prior to that, I hadn't been in London since the late 90s.

So going back to London next week, I will not only visit the National Archive, but also plan to go looking for some new aviation books. So which good bookstores are there in London where one can find high-quality WW II aviation books? I will stay near Piccadilly Circus.
