White Walls Gallery, San Francisco

Yes, they have white walls. And yes, they are quite different from your everyday galleries, where sales are all that matters. This gallery caters to all art-forms, from urban street paintings to classical fine art. The white walls reflect this open-minded acceptance of universal art. The staff is very helpful, even to the uninitiated, so no one feels out of place. The haughty crowd may well stay away, for this is a place that encourages amateurs and professionals alike, both, in terms of artists and viewers.
