Cartethyia also hates Pizza Tropicale, so Zani so far is alone in this matter.

Dialogue from the quest when you offer Cartethyia the pizza:

Cartethyia: "Ew! Just the sight of it is enough to..."
Cartethyia: "Is this what people eat nowadays?"
Rover: "I see you are a Ragunnesi through and through."
Cartethyia: "Hmm?"
Rover: "You're not going to eat it?"
Cartethyia: "No!"
