Hmm I remember living in a middle-sized city in The Netherlands that probably most things were available in good quality as long as you knew where to look. Mexican food I can't judge, but Indian or Thai or REAL Chinese food wasn't a problem, with a few options to pick often. Italian and French of course. Good burgers yes.
There's of course a difference in culture. You can't find sesos even at the best butcher shops while in Argentina they're in any medium sized supermarket. That's just stuff that nobody but the very adventurous will eat outside that cultural zone.
I can speak to the lack of real Indian food in the Netherlands, there's about one restaurant in Amsterdam which serves proper food. The rest all serve British Indian Restaurant cuisine, which is the equivalent of Febo representing all Dutch food.
