Uh... Cheesecake? [He knows what cheese is and what cake is. So. It's a cake with cheese in?

Cheese is okay. But he isn't a big fan of cake. A cake with cheese in it seems like it would be pretty gross. All melty and smelling sweet but also cheesy at the same time. Or maybe you melt cheese over it or something. Either way!] No, I've never even heard of a cheesecake before. It doesn't sound like it would taste very good.
