Fast food from around the world

There are so many fast food restaurant around us today, its unbelievable! I'm not just talking about American fast food like Carl's Jr or McDonald but cultural/international fast food restaurants like P.F Chang's, Taco Bell, Del Taco, and Panda Express. It's not a surprise to us to see a Mexican fast food restaurant or an Asian fast food restaurant whenever we step outside our doors. People enjoy eating these international food so much that we made them to fast food to have them cheap and availalbe at every possible place one can imagine. These cultural fast food are very very sucessful not to mention. They may not be good as the traditional Mexcian or Asian food but its close enough or some don't care about the traditional taste as long as its fast food. People from couple decades ago would not believe how much foreign food we eat today or how theres a fast food every mile of each other. Why are they so popular? What drives us to want them? Is it because we are tired of eating pizzas and hamburgers? Are we eating international food because we think its healthier even though it's still fast food? Are we attracted to fancy names like orange chicken and eggroll? (not sure why orange chicken is named that way even though it's not orange, and eggroll doesn't look like its rolled in eggs, just crunchy brown stuff). Whatever the reason is it's popular and everyone is going crazy about it. The question is however; will we be intersted in food from other countries like Egypt , France, Germany, India, Arabia, etc. Are we going to love them so much like our Mexcian and Asian food that we make them to fast food restaurants as well? I think there is a possibility that we might. In couple decades from now we could be walking into an African fast food restaurant ordering what maybe strange to us now. It's only a matter of time before we realize that other countries have delicious food and be eating food from around the world within few blocks of our home.
