Bookshops I keep going back to

Right, so I am NOT a reader who finishes things on time, honestly though, I've got three library books overdue as we speak, but I love a good bookshop the way other people love a good pub crawl. This is basically my Manchester bookshop circuit, sorted between gallery hops and curry mile cravings, where I've spent far too long browsing when I was meant to be somewhere else entirely.
