Things have gotten better for most people in Argentina, but at the cost of another of those 'boom for 10 years, then bust' cycles we are so used to. You can't argue inflation is rampant, I still recall the first time I came back from Brazil a pizza was about AR$10. Today the same pizza (maybe with a fancier name) starts at AR$40.
But then, 'eating out' doesn't reflect the real inflation. In that period, pizzas increased 400% in value, alfajores (a local sweet) had a similar increase from (AR$1 to AR$5), while a coffee at any bar in Buenos Aires increased around 1000% (from anywhere around AR$2 to a starting value of AR$17, most commonly AR$20+). Nice wines on the supermarket only increased about 200% in that period. Buy the same wine in a bar and you'd think you are at some fancy spot in San Francisco, they are so expensive. So it's all over the freaking shop (no pun intended).
