Most canteens can do well, with popular dishes and special cooking. Students are used to packing from the canteen or eating in the surrounding food city. There are also many take-away orders, but they can only be sent downstairs for students to take, not to the dormitory door. There are many kinds of food in and around the school. If you want to do take-away business, you must be of excellent quality and distinctive enough to attract students, otherwise you will have no advantage and can't do it.
