If you have the time and want to save a bit on meats -- beef, pork, chicken -- try going out to the wholesale meat district in Mataderos.You can take any number of buses. Just get off at around the 6300 block of Alberdi (esq. Cafayate) and walk southeast on Cafayate or Pilar a couple of blocks to Rodo. Then wander.There are tons of slaughter houses, supply stores, retail counters, etc., with great prices. I came home with a knapsack full of stuff the other day. It was well worth the trip.
