Perhaps made famous to foreigners thanks to Hugh Grant and Julia Roberts in the film of the same name, this part of London is really on the map because of the annual carnival in August, second only to Rio de Janeiro's.
If you imagine the Notting Hill Carnival as a colourful, loud and fast moving pageant, you are wrong. It is far more resplendent and clamorous, and way too crowded to move with any speed at all - the streets are not as wide as in Rio!
