Oh I am a fan. A big fan.
Popcorns and drinks are CHEAP.
On average, I spend $ 12 or so for pop corn and coke in other cinemas. I get it the portions are bigger but my small body doesn't need bib-sized popcorn.I have no choice but to eat and drink those huge portions - enough pop corn and soda to fill me for four weeks.
Movies are great.
I have seen movies that are no longer in theatre or would not be released nationwide. It's a really good option for me. Most movies are intelligent. I have yet to see Bieber 3D movie (sorry Biebs fan).
There are exhibits on the ground floor for added fun.
I love the small theatre and smell-free auditorium.
There are two restaurants inside TIFF. Cheaper-priced cafeteria style at the lower level and a higher-priced restaurant above (higher floor of course). In short, your option is cattle-class below and snob-class above ;).
Come. Come often.
