I can't pass without dropping in, Orcs Nest is a small independent boardgame, D&D etc store that's been around forever(1987)... and has the best logo. Good selection of games for younger kids too.

London’s wildest and best park to get lost in. Just follow your instinct, chase trees, go up to the viewing points and you’ll always find breathing and mindspace in Hampstead Heath. If you can, visit often, as it goes through wonderful changes over the seasons.

An obvious choice but no 'best of London' list is complete without the Barbican

Museum exploring connections between medicine, life and art. Fascinating range of exhibitions and great shop, library and cafe. Free entry too. 

Barbican, a residential estate in central London, is known for its brutalist architecture, almost a social experiment on how to live in an estate. I love walking around this area looking at the geometric shapes, the contrasting public spaces and the use of materials. The term brutalist originates from the fresh word for ‘raw’, and concrete is typically used as one of the main materials.The Barbican centre located in the centre is an arts centre and the largest of its kind in Europe, and was opened in 1982. The centre is used for classic and contemporary concerts, teatre, film screenings and art exhibitions, and houses a library, restaurants, cafes and bars. The areas’ architecture really invites you to go on a photo safari as there are great angles and light everywhere.
