I had them once when I was living in Houston, TX, USA. Unfortunately, I can’t have gluten-containing foods anymore so anything wheat-/flour-based is out. Thankfully, I can get corn tortillas. I mostly just cook things at home, these days.

I’ve eaten at a few Peruvian restaurants as well and I’m sure other countries that aren’t coming to mind right now. I just mentioned Mexican (and derivatives/fusions) as that was what the post was talking about.
