Die besten Restaurants mit Fast food Essen in Chavannes-près-Renens

I was left speechless this morning when faced with a "saleswoman" who couldn't tell me if the chocolate bars contained hazelnuts (I'm allergic). I ask him if it's praline or black? Madame answers me: I don't know, I don't eat it... I kindly point out to her that it's part of her job to be able to answer this VERY basic question from a customer... To be safe, I left with a croissant (mediocre quality by the way.) Next time, I will go to the coop.
