One of my favorite ways to kill time at the Eaton Centre. Fantastic zine selection and lots of open seating to peruse books/magazines at your leisure. I know that this is a chain/big box...whatever you want to classify it as bookstore, and that this is a deal breaker for some, BUT I have never felt any pressure from staff to purchase, which cannot be said when casually browsing in some of the smaller independent mom & pop shops.
Added bonus#1-I know that this has absolutely nothing to do with Indigo save for its location, but there is a first rate hot dog cart on Albert St. (within spitting distance) of Indigo, and I have enjoyed the hot dog/magazine combo experience on more than one occasion.
Added bonus#2-The large windows over looking the small adjacent court yard are also ideal for people watching if thats your thing.
