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.

Favourite walk at night, especially in the summer.  Quite dramatic, very romantic. 

There are three branches of this South Indian Vegetarian Restaurants across London, two in the West End. They all look pretty unremarkable from the outside, the décor is pretty basic, but don't be fooled - the food is wonderful! It's incredibly cheap and the friendly staff cater for vegans and people with food intolerances really well.

A treasure trove in the The City of London. The Archive of London. Strongrooms hold kilometres of shelving; boxes of matter that has somehow been catalogued and categorised in a traceable manner by the public, for academic, genealogical and other research. This beautiful book is from a box on Epping Forest. On the same visit, I looked through photographs of Blitz singsongs in Bethnal Green Underground station, 1980s anti-Thatcher / pro-GLC gig posters and paper concertina optical models of the Crystal Palace.

Cosy little restaurant with a giant kitchen island unit in the centre which doubles as a display and seating area. Open for breakfast, lunch and dinner with a focus on fermenting.
