IF it´s open, while at the Galería Boston, do yourself a favor and try the empanadas at La Cocina.
Place certainly doesn´t look like much but the empanadas are one of the best in BA.
They do have another VERY small place on Av. Pueyrredon and Arenales, easy to miss.
A mandatory stop when in the area. Been going there for ages.
@gracielle, IF they´re open, DATASOFT inside Galería Jardin, is the place to buy. They sell online too.
There are one of the oldest computer companies in Argentina. Did business with them starting in the late 80´s and the last time I asked, couple of years ago, it was still owned by the same guy. Quique.
