Thank you, Comus Sideways, you nailed the Japanese film despite the fact that I remembered some things totally wrong! Noodle soup /ramen) not sushi and it was the womans dream not the mans.
Please enjoy this trailer of Juzo Itami´s wonderful film Tampopo (1986)!
I would have gone totally crazy (well some say I am already, but don´t you believe them) thinking about which film this was, now I can try to buy it and watch it over and over and over again...
