I spent a month in Buenos Aires last April and had a fantastic time hitting up some of the great restaurants that the city has to offer. While there, I went to all of the places listed below (among others that I can't recall off the top of my head):
La Vineria de Gualterio Bolivar
Defensa al Sur
Cafe San Juan
Les Anciens Combattants
I'll be returning to BA in two weeks and would love to try some places that I didn't get to last time, or anything new and wonderful that has opened in the year + since my last visit. Any suggestions for new restaurants that are wowing, as well as any recent info on the restos listed above that might influence whether a return trip was warranted would be much appreciated.
