I'm planning a party for 50-60 students and would love some recommendations for somewhere to pick up cheap appetizer-type takeout food.

We were thinking samosas, empanadas, Jamaican patties, savory pastries... that type of thing, but are definitely open to any kind of suggestion. I don't think sushi would be a great idea since the food may be left out for a couple of hours.

West side Vancouver preferable, but anywhere in Vancouver would work.

Thanks!
