Fast foods have gone global. But the big American chains are exporting more than just their classic burgers, fries, subs, chicken, and pizza, they're exporting American ingenuity by adapting to local tastes and taboos. So McDonalds, Subway, Pizza Hut and KFC are changing their menus to make sure they hold the beef in India, add the shrimp in Japan, go Kosher in Israel and add the rice and spice in Hong Kong. Coca Cola gets into the act with flavors and fizzes that appeal to local palates. So when Americans stop at their favorite fast food chains around the world, they're bound to be surprised by the menu.
