There are a few chains now with burritos and other Mexican stuff
That's a good example of what I mentioned above about returning emigrants. The inspiration for them is a pi$$-poor chain of wannabe "Mexican" fast food restaurants in Chicago called Taco Burrito King. For some bizarre reason, this chain became very popular among Polish immigrants in Chicago. There is plenty of great authentic Mexican food in Chicago, but it is TBK that has cemented the idea of what Mexican food is, and should be, in the mind of countless Polish immigrants.
By the way, I've eaten at TBK in Chicago, and found it amusing how many of the other patrons were speaking Polish. I wasn't amused by the food, that's for sure. Better than Taco Bell, but then, what isn't?
Chipotle, another "Mexican" chain started by McDonalds, is another chain popular with Polish Americans. Why, I don't know. It's bland and lifeless, and a far cry from real Mexican food. When I returned to Chicago from Poland, though, my Polish friend there was quite enthused about it. I told him he's nuts and took him to several real Mexican restaurants. He was not impressed because it did not conform to his perception of what Mexican food should be, namely Chipotle.
He was also enamored of the hamburgers at a chain called Five Guys. When I took him for real good hamburgers, he was disappointed that they were nothing like the chain version. For him, the ultimate burger was Five Guys, and anything else was judged based on its similarity to their product.
On the other hand, I have taken three trips to Puebla, Mexico with my Polish friends, and they absolutely loved authentic Mexican food. Puebla is the culinary capital of Mexico and the food is ultra-diverse and to die for. However, I suspected they appreciated it so much is because their minds and palates had not yet been poisoned by the likes of TBK or Chipotle.
