There are many comments here assuming the plot is about cannibalism. People asking for confirmation are getting joke responses. So, here is a serious answer: the chef in the movie serves a 7-course meal. The first couple courses are weird. The second is bread without bread: diners get butter, oil spread, and nothing where the bread should be. Yet the courses get weirder and weirder until the experience turns into horror and it eventually becomes clear the diners might not survive the night.

The script had Daniel Radcliffe playing himself as a celebrity who wants to experience this exclusive restaurant. However, it seems John Leguizamo is now filling that role.

Alexander Payne (Sideways, About Schmidt, Election) was originally set to direct The Menu, which is interesting because he usually writes his own screenplays. Payne must have been really taken with the script.

Lastly, I hope you all have a good day.
