This is a super helpful word in Korea, because you can get pretty much ANYTHING delivered in this country.
Most usually used for food, 포장 (po-jang) literally means packaging.
So when you're asking "포장 해도 돼요?" (po-jang hae do dwae yo?) you are asking "can I have this packaged" aka "can I do take-out?"
It's pretty rare for a place to say they can't do takeout unless its like, BBQ or something that requires you to be in the restaurant to eat it, so in most cases they'll say yaaaas :)
