Food for thought...

"The most popular food in the world is not the Big Mac. It's pizza. And what is pizza? It is just a flat piece of dough on which every culture puts its own distinctive foods and flavors. so Japan has sushi pizza and Bangkok has Thai pizza and Lebanon has mezze pizza. The flat-world platform is just like that pizza dough. It allows cultures to season and flavor as they like - and you are going to see that more now than ever."
