It’s good, especially quality of most ingredients,
but it is for many foreigners as others have said, bland and repetitive. Milanesa. Meat. Empanadas. Tartas. Pasta. Pizza. Ice-cream. Facturas. And for a treat something like Locro or Matahambre topped off by a familiar old flan. A typical Argentina menu reads more like the children’s menu where I am from (which in my opinion, when going to restaurants or dinner with my Argentine friends, some also tend to act like children in insisting on eating bland and familiar things and if it’s not perfectly bland they throw a tantrum complaining of too much salt/ pepper/ seasoning/ garlic etc.)
There is still hope though. The UK/ Australia/ NZ etc. used to have this kind of reputation for bland food too - now you walk into any Pret-a-Manger or rural supermarket and you’re guaranteed to find Vietnamese, Indian, Moroccan, Thai and many more culinary influences making their way into peoples everyday lunch and becoming “normal” food rather than “exotic” food. That’s why many foreigners here, especially those from more cosmopolitan places, may find the food scene a bit boring because it simply does not compare with the variety that exists abroad which they have grown up with or become accustomed to.
I know this is a BA forum but Argentina is more than BA. Up in Salta you get far more exposure to the Bolivian and Peruvian cuisines. It starts getting more spicy (thankfully) as you move north. A nice picante de pollo Boliviano really warms the heart.
I agree with most of what you said. Food is great but can get very samey. Granted though, Mendoza has a decent restaurant scene with some good variety and good exposure to indigenous foods and neighboring countries cuisines for cheap.
