Eat (2001)

A restaurant opens for the night. The diners include: A man dining alone, who orders a plate of spaghetti that becomes his dining companion. A couple; the woman talks endlessly (and unintelligibly), as her head mutates into a variety of shapes. Her ravenous companion refuses to pay, and the restaurant reclaims its food. A family with two children; they play, rather elaborately, with their food.
