Some more food scenes I especially admire:
Easy Living (1937)-- some comedy bits set in a Horn and Hardart-style automat, fascinating to see that kind of business in operation (the coffee spigot that comes, Cocteau-arm-like, out of the wall, with a nickel slot next to it).
Hardboiled-- Hong Kong action movie by John Woo with a famous opening shootout in a tea house.
The Happiness of the Katakuris and Dead or Alive-- two films by Japanese wild man director Takashi Miike. The first is a musical comedy about a plucky family trying to make a go of a rural B&B where, darn it, the guests keep dying; the opening sequence involves a claymation uvula that escapes from the back of someone's throat and among other things winds up in some soup. The second opens with a parody of a supertough John Woo type restaurant sequence whose high point is, when a gangster who's been slurping noodles gets blasted from behind, the noodles spray every where from his wound.
Actually, there's a LOT of Hong Kong movies about restaurants-- Aces Go Places, Chicken and Duck Talk, etc.
