This is a very cute movie. I don't want to give much of the plot away but Martha is a very obsessive uptight chef who eats, breathes and lives for her job as head chef at the Lido restaurant in Germany.
There are two different scenes in it that I loved where Martha confronts two customers who complain that 1) her foie gras is undercooked and 2) the steak is just not rare enough.
Personally, I've never seen any chef do what Martha did to these diners. Any chef comeuppance stories you want to share?
