I don’t know about entertainment per se but certainly as a form of connection.

Food, like music, art, and language; are core components of what defines a ethnic or familial culture.

So food is more about engagement than entertainment.

That being said, food releases endorphins and dopamine and thus people use it as a coping mechanism which then could be argued as entertainment

But I don’t think people answer the question “are you not entertained?” With “food”. It’s just an aspect of culture
