The walls keep on changing, but there is a significant collection of works by San, Banksy, Sheperd Field (OBEY) (and i had opportunity to chat with his crew while they were putting up some new stuff and making their guerilla attack to London) to name few. The gardens will lead you towards Black Rat Press Gallery and other design departments.
Also, a great place to just hang out and listen coversations, learn about history of jazz.. could go on with it for ages.
