A scary movie in 1990s

People were sitting on the table , then a woman grabbed another woman with her long hand and then ate her, and at the end of the movie this female vampire was eating Lettuce , then she ate half of a man on a truck .
People were in a big house , at the start of the movie everything was normal but suddenly vampires attacked people,
(I was 4 or 5 when I saw this scary movie so I cant remember anything else)
