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.
The walk along the South Bank from Westminster to Tower Bridge will take you past a plethora or interesting sights and cultural hotspots. There's always something interesting going on too.
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.
