We're on one of those great international flights that leave at like two in the morning. I want to bring some additional snack, ie: subway for when I get hungry at 3am.

What times do the following places close?

Stores?
Food court out side security?
Food stalls inside international security?

Is the airport quite dead before these flights?
Is there anything to do on international side of the glass at VYR?

Thanks.
Erik
