Even though I don't drink coffee, being from Melbourne means I am familiar with the coffee snobbery that goes on (and have lived in Canberra where the 2015 barista world champion has his cafes including Cupping Room). After horrible coffee in Santiago and Patagonia, I would curious to know how the reputed new formation of coffee and cafe culture in BA would be.
Coffee Town is conveniently located in San Telmo market, where the other attractions of Nuestro Parrilla, the Sunday fair and general San Telmo-ness co-exists.
They have a list of beans from all over the world and a variety of preparations you can order. Alternatively they are very proud of their espresso which uses 3 different beans around South America. Both the Honey Press (Costa Rica) by Clever process (ARS110) and the espresso latte were smooth and excellent with no bitterness.
I had an ice coffee (ARS80) which was their espresso coffee with added ice and oddly an orange slice. It was strange. Perhaps they could make an espresso martini for me next time.
