Clearly, it's all relative. Your perspective depends on what you consider "normal," your financial situation, and your lifestyle. In our case, we dine out a couple of times a week and cook at home the rest of the time. Groceries here are a fraction of what we paid in Washington State. For instance, a good blue cheese that used to cost $25 per pound is significantly cheaper, and organic vegetables are at least three times less expensive. Items like milk, chicken, and eggs are also much more affordable.
While I used to think Don Julio was overpriced, we've found that dining well for $10 to $15 per person is quite feasible at relatively upscale places in the last few months. Contrast that with the U.S., where a tavern burger can be $20, and a beer costs $8. We purchased our apartment in 2007, so rising rents don't factor into our budget. ABL taxes for our apartment here are a fraction of what we paid in the U.S., and utilities are remarkably inexpensive compared to the States.
For someone accustomed to budgeting for U.S. prices, living here is cheap. However, it's undoubtedly very expensive for the majority of the population earning in pesos (approximately 95%).
A recent visit to Franca, a Michelin-listed restaurant, reflected the most we've spent on a meal in three months – 50,000 pesos. This included a superior bife, outstanding side dishes like asado-grilled asparagus and cordero tataki, a generous salad with organic greens, and an irresistible dessert. While we generally don't drink at restaurants, contributing to the lower cost, a comparable meal in Seattle would easily cost triple. In Seattle, fixed-price restaurants with $100 meals and a $68 wine flight are not uncommon, and prices in NYC are even higher.
In general, people living here, whether Argentine or expat, may have outdated notions of North American prices. Living expenses such as food, utilities, transportation, and healthcare are significantly cheaper here than in the U.S. when considering the exchange rate. However, the challenges faced by those earning pesos are substantial.
