The French are passionate about food, so lunches are the norm when doing business in France. These usually consist of an appetizer, main meal (with wine), cheese, dessert and coffee and normally take up to two hours. This is a time for relationship building.
Do not begin eating until the host says, 'bon appetit'. Pass dishes to the left, keep wrists above the table and try to eat everything on the plate. Be careful with adding salt, pepper or sauces to your food as this may imply you find the food tasteless. If eating in a restaurant, the person extending the invitation always pays. Be sure to reciprocate this gesture.
