은 거 드시다

eat something like that (polite)

A description in "-(으)ㄴ 거" as the object of 드시다, the honorific of 먹다 "eat/drink". Almost every line builds it with 같은 거, "something like": have you had something like doenjang stew, people who drink alcohol and the like, try something like gukbap when you come, don't eat things like cake. The honorific means the speaker is addressing an audience or a guest, which is why so many of these lines are advice from a host or a doctor to a viewer.

Register: polite, addressed to a viewer or guest
