If you want a peaceful day out of the busy city, Highgate doesn't really feel like London. The cemetery is interesting and peaceful, there's a tour of the old half which is definitely worth the money. Karl Marx, among others are buried there.

Best cinema in London!!

Morito is a few doors down from it's well know sister restaurant Moro. This not long open tapas restaurant feels like it could be in a little back street in Barcelona. The food is great, and it has a buzzy but relaxed atmosphere. You might need to wait a little while for the table, but I promise it's worth it.

This is a nice place to hangout...they have healthy food, juices and desserts! The pistachio ice cream is dairy free and really good! 

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.
