The Saatchi Gallery is a beautiful London gallery for contemporary art.The gallery has several floors with many rooms and is always filled with many collections from many artists, except during special occasions.
There are lots of interesting stuff. Some of the exhibits will definitely bring a smile to your face, like the one of the Rolling Stones brought to mine. It's a great place to hang out if you are a wheelchair user. There is a ramp access at the gallery's main entrance and there are elevators on every floor. Wheelchairs are available upon request in case you need them.
Also, stop by the cafe just outside the gallery for a nice cake and coffee, it's also fully wheelchair-friendly.
Enjoy yourselves folks.
