The Menu is a comedy-horror-thriller set in an exclusive restaurant on a private island and it gives the rich a good kicking, like The Triangle of Sadness, except here they manage to keep their food down, mercifully. (At $1,200 a head, you’d hope so.) But the diners are not spared otherwise, and it’s nastily fun, if not pure evil, and should possibly come with a warning: after this, you will never, ever wish to dine anywhere that isn’t Nando’s.
