I love going to the Drive-In to watch movies in the summer. This is my first visit to this location as we found out about it by chance. I've always gone to the other location in Oakville. The screens here are a bit smaller but it was very busy the night we went.
I'd advise you to come really early as you want a good spot and if you need any refreshments the lines are quite long. They have quite a bit of refreshments available from hot dogs to nachos to pulled pork sandwiches! Since they show a couple movies one after the other the concession area stays open pretty late. They close shortly after the last movie of the night begins. Yay!
When you park you can either stay in your car to watch the movie but some bring collapsible outdoor chairs for patios or camping. I'd recommend bringing some bug spray to fend off nasty little buggers. Some trucks reverse backwards and have mattresses for people to lie on which is pretty neat! Also, they have specials where you can fit as many people in a vehicle à la clown car and only pay the entrance for the vehicle. I would definitely come back again. Just have fun and hope your car battery doesn't die .
