My favourite book shop in Montreal. Having gone to McGill, just up the street, I would easily walk down to indigo for a spot of reading and browsing nearly every day!
There are lots of armchairs and windowsills to be had, and with the massive windows surrounding the floor, there is always plenty of light to see by.
The small cafe, despite not letting you take unpurchased bookes in, does have satisfactory fare. And (!) freely available water! (a first in Montreal)
Definitely a good bookstore to visit. I particularly like their New Age and Fantasy sections. The computer one is geared a little bit too much for newbies and often has out of date books.
