How great that you were able to find a place that takes you back to those moments you spent in your country, even if the flavors don't match too closely, at least it's close.
I think that the opening of this place has to do with the commercial opening that the government is currently carrying out and that is why this kind of places are opening. Although it was not clear to me if it is a franchise, if the owners are Argentinian or American. Anyway, from what I have read, I see that you were satisfied with your experience and that you are going to go back to eat those delicacies.

Best regards.
