European and South American restaurants are generally company-operated or franchized (although there are many affiliates—joint ventures—in France). Like the US franchises, restaurants aboard are allowed to experiment with their menus. In Japan, hamburgers are smaller because they are considered a snack. The Quarter Pounder didn’t make much sense to people on a metric system, so it is called a Double Burger. Some German restaurants serve beer; some French restaurants serve wine. Some Far Eastern McDonald’s restaurants offer oriental noodles. In Canada, the menu includes cheese, vegetables, pepperoni, and deluxe pizza; but these new items must not disrupt existing operations.
