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.

The Greenwich Observatory with its green laser beam can transfigure any night sky. If you decide to cross the Thames via the foot tunnel, make sure you look out for the green ray. You can be on one side of the meridian in a minute, and cross to the other side on the next, without even realising it.

Travelling on these uncrowded river buses is such a relaxing way to see the city's landmarks from the Thames. A really quick and lesser-known way to travel from central London to Greenwich, especially on a sunny weekend.

Go check out this very untypical gallery in the underground. You don't need a ticket and it does only take you a second to soak in the art displayed.

Great place to work and even better coffee. The roastery at the ground floor gives off a nice scent that fills the whole space. Sit near the bar at the kitchen area and look at all the delicious stuff the chefs whip up - and try their V60!
