Saatchi Gallery
Duke of York's HQ Chelsea, King's Road London SW3 4RY
The Saatchi Gallery moved to this imposing Chelsea location in October 2008, having outgrown its previous home at County Hall, but its purpose remains the same – providing a forum for the best of contemporary art, as it has done for more than 25 years. Most of the artists whose work goes on display here today are unknown young Brits or international artists whose work hasn't before been seen in this country, so you could see more or less anything, from a sculptural display to a multimedia installation, but the nice thing about Saatchi is that you're sure to see something new – and sometimes extraordinary. And it's free.
