We spend two weeks in London last year. We went there in the autumn .We think it is the best season to visit England. The weather is usually good but there aren’t too many tourists in October.

We stayed in a small hotel in the West End .It was convenient as we did most of our traveling by foot. We went to look at the places where all tourists see. We saw Buckingham Palace and the National Gallery.

We went to shopping in Oxford Street and spent too many money .What we liked most, though, was going to theatre. We don’t have the chance to see so wonderful plays at home .A lot of people say English food is very badly. We didn’t think so. It’s true that most of the restaurants are French or Italian or Chinese, but we had some very good meal.
