Virrey Cocina Urbana
The beer is a bit more expensive (70 pesos during Happy Hour) but the old building (colonial style) where the bar is located is worth the extra pesos, not too mention the terrasse (pretty rare in San Telmo).
They have delicious local craft beers and a few interesting imported ones. The food is really good too!
The service might be a bit slow (welcome to Argentina) but good things come to those who wait
