Hello, forum members: If I were to go into a restaurant to be seated or a theme park like Lotte World and the host or attendant asks me how many people are in my party. How would I say, "Two adults and two children"? My attempt: 어른 두명, 아이들 두명 있어요. And what do you call a highchair for a child in a restaurant? 아이들 의자? Thank you very much!!
