Sit. Drink coffee. Buy Leica. Leave penniless.

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.

The Sackler Crossing is part of a route through the 120 hectares of Kew Gardens, designed by John Pawson in 2006. Set low to the surface of the lake, it seems to float across the water.

I only made my first visit to Troy Bar fairly recently but it's already become a Friday night regular, and I feel like I've wasted a lot of nights not being here. Caribbean food, 4 Red Stripe for a tenner, an incredible house jazz band and as good an atmosphere as you'll find in the city.

Excellent gallery. It has big rooms which often feature large pieces and admission is free.
