I spend many hours in the bookshops along this stretch, namely Henry Pordes for second hand books and new discounted titles (pile on left of photo), as well as Koenig Books for new art books with lots of great discounts in the basement. (photo right). In 2001 the rents for much of this strip were increased to align them closer to market value but thanks to public support they were reduced again. Unfortunately some bookshops still closed down; Koenig replaced the beloved Zwemmers - a real institution - but thankfully still provide great books, although others are no longer bookshops at all.
Being an East London boy at heart I am partial to an occasional fix of café culture. Pellici's has been running since the start of the last century, to which me, my father and my father's fathers have all enjoyed its mix of tasty Italian/London grub and energetic atmosphere. If you're visiting, make sure you drop by, as it will provide a valuable, forever-depleting education into what East London is really all about.
