Foyle’s is quite possibly my favourite bookstore ever (with the exception of Shakespeare & Co. in Paris, for obvious reasons). I could browse there for weeks and never see everything. You may be surprised that I only came out of there with one book (a biography about Sartre & Beauvoir, and their relationships with others), but I didn’t have too much suitcase space to spare. But, even better was that I finally met the most excellent Aleksandr Voinov. 
More posts about my trip will be forthcoming!
