You should visit Nobrow, a shop in Shoreditch, only a few mere blocks from the grave of William Blake in Bunhill Fields. The shop is a beautifully curated little gallery slash comics slash illustration space. Definitely worth a look. It was only a block or so from our hotel, but we found it at a comics fair in a park several miles west. Magical.
Below you will also find a sketch I made during dinner the last night there.
