Varsity is one of my favourite movie theatres in the city - in fact, I try to avoid going to any of the big theatres if at all possible. When you're looking up movie times on www.tribute.ca make sure you don't get duped by the VIP showtimes because you can't attend those showings as a layperson.
The self-serve kiosks are decent and almost always in working order, but beware of sold out shows. You'd be wise to show up early to pick up tickets as the theatres aren't THAT big and sell out quickly on popular nights. I'm also a big fan of the Indigo downstairs for killing time while you wait for your friends to show up. Usually I buy my tickets and then head straight for the magazine rack in Indigo while I wait.
