@anotherbob, the argument too often made by food snobs about America's versions of Mexican, Italian, or Chinese foods that these foods are somehow unauthentic is nuts. Even more nuts is that the versions of these foods found in America are somehow less tasty is even more nuts.
Good recipes and well made meals are delicious - in any country. The idea that somehow Americans are unable to recreate ethnic dishes is not just snobby, but disingenuous. Of course we can make and do make great ethnic dishes that can and do hold their own. To top it off, we often make them better. Case in point. The Burrito, Fajitas,
taco, Chimichangas, and nachos are true American inventions (Nachos is barely Mexican, but the case can be made for it as being so). American pizza runs circles around anything I've had in Italy (Yeh, you can find good pizza in Italy) let alone many of our pasta dishes can and do taste better - (not always - but you can find places that do it superbly so). Having traveled extensively through China and Southeast Asia, I find our Chinese food can often out pace what most people will find in China. Our International student from Xian who lives with us is absolutely certain that Panda Express is proof there is a Heaven.
I always make a point to eat locally when traveling. It is soooo hit or miss. I've had Guinea Pig in Cuzco and Equador and I've had it here in a Peruvian restaurant in Palm Springs. I'll take the version here in Palm Springs any day.
America has some poor examples of ethnic restaurants. But we also have many good examples as well. But more to the point, the immigrants who came here found they were FREE to experiment and in many cases improve wildly upon the foods from their home countries. Orange Chicken, New York Pizza, and a plate of Fajitas are just a few examples of foods that are not just authentic, but elevate the dishes to the next level. A well-made Chimichanga in Tucson comes to mind. Yes, China, Italy, and Mexico all have dishes that are uniquely their own and typically can only be found in their home countries. But if those dishes are ever imported to America, you can be sure they will grow, develop, and improve.
