Well, why should we change the way we eat? Only because a handfull of foreigners wish it? How arrogant is that???
If you don't like argentine food, just cook whatever you like at home or open a restaurant...and treat yourself on one of those modern dishes like chicken wings on sushi rice with some creme caramel on it.
And good for Perú that they have such a highly regarded cuisine.
I've visited over 50 countries so far...give me a good 'boring' asado anytime!
