Located underneath Waterloo Bridge on Queen's Walk, the Southbank Book Market is one of London's best kept secrets. Just outside it's open daily, come rain or shine, and you can browse for hours through hundreds of second-hand and antique books, on any topic imaginable. I actually walked through this, but couldn't spent a lot of time there, as I was with some friends and we were running late for a play we were going to see at a nearby theatre. But, it looked amazing, and when I go back to London, I'm making more time to go there.

Huzzah!

Something for everyone, right?
