I think number 8 is from the movie Tampopo. http://www.imdb.com/title/tt0092048/

In this humorous paean to the joys of food, the main story is about trucker Goro, who rides into town like a modern Shane to help Tampopo set up the perfect noodle soup restaurant. Woven into this main story are a number of smaller stories about the importance of food, ranging from a gangster who mixes hot sex with food, to an old woman who terrorizes a shopkeeper by compulsively squeezing his wares.
