This is a wonderful little bookshop just off of Brick Lane in London. They have their books sorted by theme (e.g. "leaving home", rather than genre, author, etc) and the staff are lovely. I love popping in for a quick browse every so often β but even if I'm going to window shop I tend to leave with one or two things :)
The back of the shop is a gigantic mirror, which makes it look a lot bigger. Every time I'm there I get tricked by it for at least a couple seconds, which is very humbling.
