The website for The Menu explains the plot:

A couple, Margot (Anya Taylor-Joy) and Tyler (Nicholas Hoult), travel to a coastal island in the Pacific Northwest to eat at an exclusive restaurant, Hawthorn, where the reclusive, globally celebrated Chef Julian Slowik (Ralph Fiennes) has prepared a lavish tasting menu for select special guests. Joining the couple are three young, already-inebriated tech bros, Bryce, Soren, and Dave, an older wealthy couple and repeat clients, Anne and Richard, renowned restaurant critic Lillian Bloom and her slavish magazine editor Ted, and a famous middle-aged movie star (played by John Leguizamo) with his assistant Felicity.
