At first we tried popping our own but even a little home-style hot air popper set off the sensitive alarms in the lobby, causing the hospital to start evacuating before the source of the 'fire' was found. Oops!
So in the early years the old Memorial Area, The Vic, then Odeon helped us out by supplying us with popcorn - huge bags, very reasonable, a low-salt version just for us! (all that salt is not great for anyone and even worse with meds some of us take) Capitol Six and Oak Bay Rec, The Roxy have helped out in a jam, bless their little souls.
Finally I bought a semi-commercial popper and we pop it at home, small custom batch corn just for you. With real butter - all for a buck. Best deal in town.
