I like this theatre. It's located diagonally across from the Eaton Centre and occupies the top floor of Toronto Life Square. You'll have to take some escalators up but you'll come across a Starbucks, Futureshop and a food court before you get to it's level. There are a few restaurants on the top level including Jack Astors, unfortunately the Woo buffet there has closed down for good.
The theatres have decent seats and it's pretty well maintained. The video and audio or those of newer theatres so you won't really get stuck in that one crappy theatre that seems to only house art house movies.
The thing that I hate about this theatre and possible all AMCs is how terribly slow and poorly designed the self serve ticket booths are! Please AMC fix these things. I'm pretty sure old school Commodore 64s would out perform these things.
