is the greatest film featuring Helen Mirren in a toilet cubicle wearing some outrageous underwear but that's not really the same thing is it?

Tres disgusting

Japanese film from 1985 about a noodle bar. Directed by Juzo Itami. Saw it when it came out, but have never seen it again since. Remember it well, though. Really nice film.

(note: video proper starts after about 40 seconds)

In 1871, Babette, a famous French chef, takes refuge from the violence in her homeland in a small Danish village. 14 years later she wins the Paris lottery which would allow her to return to her former home in style. However, she decides instead to use the money to prepare a delicious dinner for the sisters who took her in and their small congregation of strict Calvinists on the occasion of the founding pastor's hundredth birthday.

The sisters agree to accept Babette's meal, but they begin to worry that the meal will be, at best, a great sin of sensual luxury, and at worst some form of devilry or witches' sabbath. In a hasty conference, the sisters and the congregation agree to eat the meal, but to make no mention of the food during the entire dinner.

One of the sisters' former suitors, now a famous general, reappears as one of the guests. He is unaware of the other guests' austere plans, and as a man of the world and former attache in Paris, he is the only person at the table qualified to comment on the meal.

If you've not seen the dinner sequence before watch and wonder:

was a pleasant surprise - saw it at the flicks without knowing anything about it. Wikipedia says: The Last Supper is a 1995 film directed by Stacy Title. It stars Cameron Diaz, Ron Eldard, Annabeth Gish, Jonathan Penner and Courtney B. Vance as five liberal graduate school students who invite a string of right-wing extremists to dinner in order to murder them.
Well worth a rental.

subtitled Chinese film IIRC. Years since I saw it but I remember it being enjoyable

The meal prepared in the first 10 minutes of the movie should inspire you to start cooking.
