Must be 2 Argentinas...... Maybe 2 South Africas as well
Hello from Brisbane.
Been to both countries on many occasions and am not sure if there is another Argentina on the planet following your original description and list of observations - which was a bit of a case of damned with faint praise at best.
Found the place to be genuinely enjoyable, people were friendly, food, wine and beer excellent, accommodation reasonable and my experiences at Pistarini Airport has been no worse than anywhere else and certainly no worse than Oliver Tambo International in Johannesburg.
Always enjoy a steak and a bottle of wine in the Republic too, but think you might be having a wee tug of yourself if you genuinely think the quality of beef in South Africa is anything better than anywhere else on the planet - certainly OK but I wouldn't reckon it is particularly superior to the local produce here to be honest. The Argentine parillas turn out a reasonable product, however much is excellent and some mediocre. Depends on what grabs your fancy and your mood at the time.
I guess we all go to foreign places and for some it is a great experience and for others a disappointment.
