Choc Star is a mobile chocolate shop selling all sorts of homemade delicacies. Hot chocolate, cupcakes, Malteser muffins...you name it. Petra Barran spent three months giving the Leyland DAF (the van) a makeover. The inside is complete with Neisha Crosland wallpaper, pink neon-underlit shelves and cupboard handles made of silver spoons. Find her on Brick Lane (London) on Sundays and at all the big Summer festivals. She is on tour at the moment.
