Teeny, French cafe with amazing pastries, great coffee and incredible croque-monsieur. Long table in the front and small garden in the back or take away and head to Highbury Fields, which is only a couple of minutes away.
I couldn't decide which coffee shop to feature so here's the first, Store Street Espresso. It's right round the corner from work and a great place to chill out at lunch time and get that kick for the afternoon. Compared with the other independent coffee shops in the area (Wild & Wood/Lantana/Tapped & Packed) the interior's minimal and light which is great. Anyway coffee's really good and so is the food.
The best thing about any charity shop is that you never know what you are going to find. I have a well tested route around London that includes all of my favourite charity shops. This Oxfam has a great selection of books and often turns up some interesting clothes too.
One of my favourite things about London is the underground transport system itself. I love the design of the information systems and the stations have so much history — some of them dating right back to the 1800s.
