G.F. Smith's permanent showroom, in Central London. Visits are by appointments only — But I would definitely recommend making the visit. All of their stocks are beautifully archived, along with example publications, and a rotating series of paper installations in both the window & basement, courtesy of Made Thought.
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.
Netil360 is a great roof terrace bar near London Fields in East London. It is situated on top of an ex-Hackney Council Building. We were one of the first design studios to move into the building while it was still being converted into a creative hub. It is great to see that this place is still vibrant. It definitely has one of the best all around views of East London. I took this picture (facing South) in the summer of 2018. It shows the gasworks near The Oval Space in the mid-ground and the Shard as part of the London skyline.
