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.
Present is a menswear shop with an award-wining espresso stand inside. They also stock books, cool magazines I’ve never heard of, and random things like soap and tins of shoe polish. I like to buy bags here.
