There is a major lack of excellent (not pretentious) bookstores in Toronto. Chapters and Indigo are not among them.
I absolutely adore Book City at Bloor West. They have a huge assortment of titles and categories that are actually in logical order.
My favourite part would be the staff. They truly set this book haven apart from others with a simple two-word idea; customer service. Such a simple concept, yet surprisingly hard to grasp.
