Frank's bar opens on the roof of a multi-storey carpark in Peckham every summer. It's great to go for a drink and get this phenomenal view of London. I love the design of the bar, which is different each year, and the exhibitions are always interesting.
The second coffee shop has to be Kaffeine. Having only recently come across this one, I was certainly impressed and they may even have the best coffee I've had, since a short stay in Portland, Oregon.
A great walk down an old abandoned rail way from Finsbury Park to Highgate. Most of the original platforms are sill remaining so its an interesting place to explore...
