Goofs

In the opening shot of Margot lighting a cigarette, the cigarette color changes from all black (presumably a clove cigarette) to a traditional looking tobacco cigarette.

As Margot approaches the silver door in Chef Slowik's house, light can be seen through the keyhole. When she opens the door, the room is dark.

When Chef Slowik is asked by another chef to taste the sauce, the spoon being used can be heard being put into the saucepan afterwards. Something a chef would never do as it would contaminate the sauce.

Although Margot orders Julienne fries with her cheeseburger, she is served crinkly fries instead.

Dairy cow meat is known by farmers to be less tasty than cows bred for meat so there is no reason why the chef would only serve "dairy cow meat" as stated by Elsa.

However, there are good reasons: the belief that old beef is tough and flavorless is being challenged nowadays. It has been described as tasting of cream, milk, and grass, a clean flavor profile and sweet aftertaste.

Before the bread course is served, Slowik gives a speech about how little farmland is used for fruits/vegetables verses grains. The speech is misleading since it doesn't consider the soil each seed type would need to grow, doesn't consider comparative advantage in growing crops and doesn't take product demand into account.

However, he wasn't giving a comprehensive lecture on agricultural economics. He was comparing them.
