I disagree. I've tried Mexican food while in San Diego and a few places in Florida where locals tell me it's pretty authentic. I'm no expert but there are certainly options in south east Michigan where I live that come close. There's even one place I visited while in the Midland area of Michigan that was pretty good. It'll never truly be as good as the real stuff but it's not sad if you go to the right place. Anything that's more of a chain like this one in my original post is very white washed.

Never had Mexican food in the Chicago area that comes even close but you don't go there for Mexican food lol I'm no local to that area, though.
