Answer:
in France breakfast is usually light : a hot drink (coffee, milk, chocolate, tea) plus some toasts with butter or jam, or a bowl of cereals. Lunch and dinner are more consistent: a small hors-d'oeuvres, main dish, some cheese if you want to, and a dessert.
It is usual to eat all the meals at the family table (or seated in the canteen). Hours are set according to your timetable, but most families like to eat together. A common routine may be : 7 or 8am, breakfast - about 10 to 15 minutes. 12, 12:30 : lunchtime, for about 45 to one hour, with your family or colleagues; 7:30, to 8:30 pm: dinner.
