To the original poster - I'm not criticizing you with the following, but rather the article itself. Don't take it the wrong way
I've never been very impressed with the Huffington Post. Seems to me a lot of opinions without being backed up by too much fact.
For instance, their comment about "some of the best beef in world" is a concept that may be a bit out of date at this point, I believe. It reminds me of the Argentine star (can't remember his name) who is touting for Avericar in the movie theater commercials nowadays - "ya lo saben que tenemos las mejores carnes..." (paraphrased).
Unfortunately, a lot of people don't seem to remember how really, really good the beef was here some 4-6 years ago (and before, of course), and how quickly downhill it's gone as the Argentine government loaded up the beef export industry with so many tax burdens that the majority decided to switch to soy production, which is much easier to grow, has a greater commodities market, etc. Which of course, led to the downfall of a great industry here in Argentina as Argentina started importing beef from other places, such as Paraguay (leading to a huge rise in beef prices for the poor in Paraguay, BTW). It also led to many of the remaining beef producers in Argentina to go to "new-fangled" production methods and feed the cows corn and other such, in place of free-range feeding, in an attempt to be more efficient. I've gotten to where I've switched almost entirely to pork and chicken when I go out to eat because of the consistent disappointment of cuts such as Lomo and Bife de Chorizo and Ojo de Bife served in most restaurants. you can't even be certain of getting a good cut of beef in an expensive restaurant in Puerto Madero - one of the biggest, most famous (and most expensive) beef places thee, I went to about 6 months ago, paid something like 300 pesos for an Ojo de Bife and got a grissle-ridden chunk of meat for my money. Oh, you can still get a good cut from time-to-time and place-to-place, but it's a very hit-or-miss proposition in my opinion.
As for the pasta - I have to admit, most of the pasta they serve here is not bad and even good at times, though I don't think it comes close to stacking up to places like Bologna, Ravenna, Venice or even Rome in Italy (places I know something about personally and have eaten some spectacular pastas there) as far as pasta itself goes; but the sauces that are common here, outside of a very few places, are quite poor in my opinion. Could be that someone likes the sauces here, but no one can tell me convincingly that Buenos Aires, at least, has "Italian grandmother" level sauces - which to me are at least as important, if not more so, than the pasta itself when consuming.
As to submarinos - well, I suppose that must be a matter of taste. Personally, I much prefer a hot chocolate made from Nestle's Quick (which I don't really like all that much) simply because the few submarinos I've had here came with waxy chocolate which was not very tasty and didn't melt very well, leaving little chunks of waxy chocolate in the drink.
I think the milenesa provided here rarely, rarely looks like was presented in the photo, although I've had some that are not bad. Biggest complaint I have against milenesa here is that apparently the cooks must be very frustrated and pound the meat with their hands to the point where it's a thin paper-sheet of meat that gets overcooked and has the consistency of fried shoe leather inside what is often a relatively hard shell of over-fried bread crumbs. I have to say that I've had a number of good milenesas at Club de Milenesas, but they don't come close to stacking up to the taste and flavor of what I'm used to from Texas with chicken fried steaks and a good cream gravy (the two of which I can make that even Argentinos I know have come asking me to fix dinner instead of going out to have milenesa - once they get over the relatively little bit of black pepper I put in the flour and the gravy...).
I won't go into the rest of it. I've learned to survive here on what I, personally (as well as almost all of my expat friends), consider to be not-very-tasty food (or, what's tasty, simply being tired of eating the same thing because of lack of choices) by finding the places that have good parilleros and know how to grill a piece of matambre de cerdo (for example) so it comes out perfectly singed (particularly the fat on the outside!) but still juicy in the middle and not pink and a good flavor of olive oil and smoke mixed together on the outside (di Carlos, Marcelo T de Alvear near the corner of Montevideo). Or ask El Cuartito to put their pepperonis on TOP of the cheese before they cook it instead of burying them under the cheese where the oil doesn't get a chance to mix with the rest of the pizza (although their crust has been getting soggy lately instead of nice and crispy on the bottom). Or, learning to be a good cook myself, experimenting with various recipes and the available spices and other such things that are available here for when I need something that I just can't get here at all.
Food isn't the most important thing in life, that's for sure, but it can be important, particularly when one has moved from what one is used to, to another world. Most of what the HP article referred to could indeed by chalked up to personal taste, but the "some of the best beef in the world" comment made me want to comment on the article, wondering if the person who wrote it had spent any time in Argentina recently or maybe has just seen the Argentine star who touts for Avericar say so.
As far as Argentinos being better at life - I would say they do some things better than we in the US do, it's one of the the reasons I chose to continue to live down here after my original business folded up, but I would NOT want to live here if I was earning money in pesos at a level that most here do so. I question how many people know people at all levels of society here when they make the statement that Argentinos are better at life. It's easy to happy with life, polite, helpful, when you are flush with money but I know too many people on the middle and lower rungs of society who would beg to disagree with that statement.
