Sajhamitra ji,
I don't know about you and for me english is not my first language. 'Cuisine' the word that guy used is not commonly used. I am sure if you had not gone to English medium school, that word probably made you wonder too. That guy genuinely asked what did it mean to the anchor. And that is right thing to do rather than thinking what it means and answering completely wrong. And what the guy did. He laughed. He laughed and laughed making the guy he is interviewing nervous to answer it. I would rather be embarrased guy to have asked what I did not know  than to be that imbecile, impolite and ignorant guy who thinks everyone should know english as language. It takes courage to ask, at least he had one.
