The 2 sports bars I mentioned are Locos por el Futbol and World Sports Cafe. They are both in Recoleta near the famous cemetery where Eva Peron is buried. The former is on a sort of square which borders the cemetery. The latter is on a side street, also bordering the cemetery, at 1 end of the square. I don't know if you've been to BA before but 2 pieces of advice: 1) Don't get in a taxi unless you've had a large drink beforehand. The driving makes Naples seem like a country village. 2) BBQ beef is the main fodder but watch out because side dishes e.g. chips and salad must be ordered separately and cost as much as the meat.
