I grew up in Brighton which is full of cheesy bars like this. If you can handle being surrounded by multiple screens playing Kylie at full volume, its pretty much the cheapest bar in central london. The cliental is so varied its great for people watching and completely un pretentious.

Great little neighbourhood hangout. Delicious food, good coffee and open evenings Thursday-Saturday. Next to the Sylvanian Family shop!

I love living in cities with a river and the Thames is so wide! It is one of my favorite things about London.

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.
