What's a good dark roast coffee at home here?

[paulo]

I'll also add LAB tostadores, one of the old school cafes that has their own brand (in Palermo Hollywood area). I haven't been in a long time but I remember them having a darker roast at some point, as well.

I share OP's preference for dark roast. For expresso based coffee drinks like Americanos the disgusting trend for lighter roasts seems to be spreading where I currently am (Philadelphia) and where I was last week (Montreal) but I was advised to go where italians drink their coffee to avoid this sort of taste trauma. Buying beans roasted and ground for expresso surely must be possible in BA? Hats off to you all for hanging in there.
