Saatchi Gallery

With a brand new location, this is one of the most important private and stunning museums in London. It houses contemporary art in 15 rooms spread over three floors, in a beautiful building. Admission is free, they allow you to take pictures, and usually have several interesting collections from around the world. It's in Chelsea, on the fun and lively King's Road, so afterwards you can have a bite to eat in one of the many restaurants.

I went with a group and two teachers and had a good time admiring all the work of one of the best group of the music history : The Beatles!
