Can departing ticketed passengers bring food and beverage past customs, and are food (e.g. roasties bbq/deli rice box) and a takeout drink cup allowed to be brought onto a plane (to be consumed on the plane)?
If yes, what are some Terminal 1 restaurants that can serve some sort of food that will survive a few hours on board the flight? The bottled milk tea from Tsui Wah seems to be an ideal size. Too bad Ah Hung's Delicacies is in Terminal 2, not sure if I can make it over there or way out of reach.
