I haven't seen The Menu, but try watching The Bear instead. They demonstrate this level-of-service & mentality and it's much more sincere than you think.
Oh, but what a letdown to have someone watch that as their introduction. One of the very best moments in the entire series but which can only be appreciated by watching the entire series.
The Menu is... overly sincere, I won't spoil it, but it's the "Restaurant as cult environment" movie. In fact the question of lacking sincerity is framed as "the audience casually disregards the immense effort and dedication requires to achieve what you demand."
...Now that's probably using restaurants as a metaphor for the film industry, but either way the point holds. I'm not put off by insincerity, it's forced, false intimacy as a product or a service goal that bothers me. Good food, good (not fawning) service is more than enough for me, I don't need this kind of race-to-the-bottom Michelin stars seem to inspire.
