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.
I really enjoy this vegetarian restaurant. It has everything from amazing healthy soups and salads to healthy dairy free desserts...my favourite is the raw chocolate tart with dairy free coconut ice cream!
Wood-fired, Neapolitan style sourdough pizza in South London: soft, airy, slightly chewy and very light thanks to the extra-long dough maturation. Family friendly small venue walking distance to the Horniman Museum.
