In between soho and covent garden. There ares lots of great independent shops on this street. Dover bookshop, magma, super superficial and Mint to name a few. Also if you want a cheap lunch on your work break Cafe No.1 is amazing. £2.50 jacket potatoes with cheese and beans.

Go check out this very untypical gallery in the underground. You don't need a ticket and it does only take you a second to soak in the art displayed.

If you want to eat a good cake this is the place! They have so many cakes to choose from but the best one is the white chocolate cheesecake. 

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.
