In the Marriott CasaMagna (literally next door to the JW Marriott - 3 minute walk) there is a brand new Argentine steak house which was awesome! We were there in November, two days before opening, and there was a "trial run" for the waiters that we happened to walk in on. They said they were just learning and asked if we were Ok with that. Best darn steak we ever had!!! Sorry I forgot the name and when I checked their site the name of the previous restaurant "La Capilla" is still posted. Kind of pricey, but well worth it.
