One of the older cafes in the country, and South American cafe con leches just make sense.
Sunday antiques fair - tons of great people watching, weird trinkets, and a hint of culture.
Head over to Palermo Hollywood for some grubby lunch.
Best parrilla in the city, and used to be fairly priced :) Bife de chorizo con dos malbecs, por favor.
Late night snacks, total tourist bar, but since I'm friends with the owners and always had a great time there, have to rep it!
Highly recommend a furnished short-term apartment rental, with the folks at Oasis Collections. Quality places, better prices, more freedom, and a truly awesome clubhouse!
