Just above the Dorfman Theatre lobby at the National Theatre, is the entrance to the high-level walkway, a public walkway that overlooks the National Theatre props and scenic workshop. It's free and is a unique chance to get a glimpse of what happens backstage. I love popping in when I'm on the south bank, as you get a completely different sight each time, depending on which production the workshops are working on at the time.

Quick, easy, cheap thai food. It's fairly new to me, but easily makes this list.

Full of fine books, nice owner and his beautiful mellow dog. If you like digging for books on most subjects you can strike lucky here.

London is so vast I am forever coming across new hidden gems. Walking around the streets and getting lost is the best way to find London's best kept secrets.

Nice place for a cake and coffee.
