Lee GyeongMi	여보, 두 분 편하게 얘기 하시게 그만 나와. Honey, let them talk. Let’s go.
Gang HyeokSoo	왜 우리 지금 진지한 얘기 하고 있는데, 이 사람. Why? We’re having a serious conversation right now.
Lee GyeongMi	나와. 맛있게 드세요. Let’s go. Enjoy your meal.

맛있게 드세요 (Enjoy your meal / Bon appétit)

맛있게 – deliciously
드시다 – to eat (honorific)
- 드세요 – polite imperative form of [드시다]

Casual – 맛있게 먹어
Semi-polite – 맛있게 먹어요
Polite – 맛있게 드세요

>> when speaking casually, the verb [드시다] should be replaced with its casual equivalent, [먹다]

>> one may respond to the expression by saying [잘 먹겠습니다 (polite)/ 잘 먹을게 (casual)], meaning “thank you for the meal/food.”

>> hosts would often modestly say [차린건 없지만 맛있게 드세요], meaning “there isn’t much food, but please enjoy your meal.”
