This looks to be really well done!
London: A Visitor's Guide, by Craig Cross. It's a brand new edition, updated just last month (September).
It's 1125 pages long! It's
free right now. Wow.
Going to London is a pipe dream for me for the foreseeable future, but I've downloaded it just to thumb through the pages and educate myself a little bit about that great city.
