I find the quality of vegetables in the supermarkets to be quite disappointiong, especially considering that Argentina is an agricultural country. You can get better quality from some street vendors however there should be fresher lettuce and other vegetables, and greater variety, in the supermarkets as you will find in many countries. There are many bakeries in BA but my experience has been that almost all are quite poor. They use lard instead of butter, lots of artificial ingredients, have little imagination and often sell products one or two days old. Even Dos Escudos, probably the classiest of the bakeries, does this. It's true that Argentine beef is generally healthier (lower cholesterol) and I quite like bife de lomo however I find other cuts such as roast beef better in the US. I have heard that Argentine beef producers are starting to get away from grain fed beef. Is this true? Maybe someone out there has some information. As for chickens, I believe they are raised in the same way as other countries - not grass fed. I am used to eating organic chicken and find chicken in Argentina tasteless.
