는 거 있다

is there anything that...?

Asks whether a thing of that description exists, most often as an interview or a shop question. Four of the eight lines here are 생각나는 거 있- 'is there anything that comes to mind', put to a guest: 야스민 님, 뭐 생각나는 거 있으세요? Another asks a shop for a type of item — 신맛 나는 거 있어요? The tag versions 있잖아 and 있죠 do something else: they point at what both of you already know, as in 그 이탈리아 사람들이 먹는 거 있잖아 'you know that thing Italians eat.'

Register: polite forms dominate here (있으세요, 있나요)
