We lived in Recoleta for 20 years and recently moved to a small town in the provincia de Cba. The food available here is much more limited than what we were able to find in BA. The vegetables here are all old and bad, for the most part. Try those stores that polostar mentioned. The fish stores on that block do not have good fish. Be wary! We bought our bread at Lepe, the panaderia owned by those two guys who have a segment on the gourmet channel and it is very good, although expensive. Also, there are some organic growers that deliver to different parts of the city, in Recoleta it was twice a week. Their veggies were very good. I don't remember the names so you will have to google that. Barrio Chino has some good things and we went there about once a month. I agree it takes a bit of time. We are retired so we have plenty of that and enjoyed looking and sometimes finding good quality produce and meat. The average diet, as serafina stated is limited and most probably contributes to the lack of available food items.
