Corrected entry: On Ben and Andie's first date, they are seen eating lobster. But later on in the movie when Ben serves her lamb, she says she is a vegetarian.

Correction: And at the vegetarian restaurant she was going into the kitchen and eating meat. Andie was not a vegetarian. She was just saying this to annoy Ben after he had cooked a meal for her.

Correction: Plenty of vegetarians just eat fish. They are called pescatarians.

Correction: This is more of a fault on Benjamin... he didn't realise that she had eaten meat prior to their vegetarian date.
