I know nothing about supermarkets in Europe, but in North America, ie, the USA and Canada, supermarket bread is low quality and from giant corporate bakeries.
I never buy bread at a supermarket in either.
I buy bread, in Buenos Aires or in the US, from small bakeries that bake every day, and use quality ingredients.
I have been here long enough to remember when there was no Pan Quotidein here, (their first argentine location was in 2012) and in those days, it was much harder to find decent bread, but now, there are at least a couple dozen good bakeries that bake bread daily, all over the more affluent barrios.
Probably harder to find in Villa Soldati than in Nunez, but there are a lot of them, and many will send em right over to your house by Rappi.
