‘베이글은 데워 드릴까요?’
‘데우다’ means ‘to warm something cold’. So, when you order a type of bread at a cafe, the staff asks, ‘데워드릴까요?’ If you want to warm it up and eat it, you can ask ‘Please heat it up.’
Many Koreans often misrepresent it as ‘데피다.’ ‘뎁혀드릴까요?’ can be taken as the same meaning as ‘데워드릴까요?’.
‘테이크아웃 할게요.’
In Korean, you can say "매장에서 드시고 가세요?". The word "매장" means "store, shop" in English. When you choose to eat or drink at the store, you can respond with "네, (매장에서) 마시고 가요." which means "Yes, I'll drink it here (at the store)." If you prefer to take it to go, you can reply with "테이크아웃 할게요" or "가지고 갈게요," which mean "I'll take it to go." Additionally, a mug or glass that can be used at the store can be referred to as "매장용 컵" or "매장용 잔," and a disposable cup for takeout is called "일회용 컵.”
Just to note, '드시다' is a polite expression for '먹다', and when it comes to beverages, you can use the expressions '마시다', '먹다', or '드시다' interchangeably.
‘컵홀더랑 빨대 필요하시면 가져가세요. ’
In Korean, '컵홀더' is a term used to refer to a 'cup sleeve.' It is a Korean-style expression that combines the words 'cup' and 'holder,' but it is not used in English.
‘A straw’ is ‘빨대’ in Korean and the box used for carrying beverages is called '캐리어' in Korean, which is the same as the English word 'carrier.'
