An obvious choice but no 'best of London' list is complete without the Barbican

Everyone should visit this absurd restaurant once in their lifetime. Its over-priced, mediocre food but the decor and ambiance is like nothing else in theatrics and campery. You are met on arrival by a white velour 'napkin' artfully screwed up on your diner plate. Absorbent, not? Fabulously awful, yes.

French Bistro style restaurant. Cozy atmosphere 

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.

P Franco, wine shop, bar and restaurant. Amazing wine, delicious small plates (guest chefs) in a very lively atmosphere. The wait for a spot to sit down is worth it.
