I should have seen the handwriting on the wall when I heard how the locals pronounced some of the Spanish names of streets, towns, etc. Very strange.
You think Colorado is strange? Try Virginia. Buena Vista is Bee-ewe-nah Vista!
As to your story, my wife and I have some friends from Venezuela, and she decided to cook dinner for them early on in our friendship. She is a great cook (her Spanish rice is unsurpassed as is her Abondigas). The meal was excellent! Except for one thing. It was WAAAAAY too spicy for our friends! They cooked us a meal for us the next Christmas and it was definitely different. Not spicy, and more what you would expect to find on a NE family's dinner table (roast pork loin, a chicken salad that you have to taste to understand, and a banana leaf thing that kind of looks like a tamale, but is nothing like it - stuffed with meat, olives and other vegetables).
I have known for a long time that the only thing Mexican about Taco Bell is the Mexican Chihuahua.
One of our favorite restaurants at home is a little cantina run inside a Latino Market. Their tortillas suck! But they do have the best chicken Flautas I have ever had. And my wife loves their Sopa de Res (just not the cactus part of it). And the proprietors? From El Salvador!
So there is Mexican food, and there is Hispanic food, and the 2 are not the same. Which is better for those who love to eat different foods!
It is also the only place (well them and other Latino markets) that sell actual Chorizo, not the American version of it.
