San Francisco is a lovely city in a beatiful day. it's got lots of great buildings and places. It is smaller and more modern than London. London is more interesting than San Francisco, has a lot of teather and museums. The americans are usually more interested in the money than culture. The architecture in London is incredible and very stimulating, and the parks and markets are wonderful. San Francisco is more dangerous and more violent than London. I feel save living in London. The public transport in San Francisco is more terrible and more expensive than in London. It takes me one hour to get to work and the journey is ussually stressful. London's dirtier too and much more polluted than San Francisco. But american drivers are more agressive than english drivers. The restaurants in London are more expensive but the attention is better.
