“One thing is for certain: you can’t miss Nelly Duff’s spectacular shop front in the heart of Columbia Road. It is a super-friendly screen-print store and edition house and one of London’s first commercial street art galleries. It exhibits and sells original screen prints by artists like Gaia, Angelique Houtkamp, Eine, Mr Wim, Dave the Chimp, and Patrick Thomas. Nelly Duff really supports emerging talent and works closely with the art schools to put on unique shows and produce special-edition releases. I’ll probably ruin their 'street cred' now, but David Cameron gave Barack Obama a '21st Century City' canvas by one of the store’s favorite artists, Ben Eine. Sorry, Nelly!” —Jasper Conran 156 Columbia Rd., 44/(0)20-7033-9683.
