Rated among with best 50 restaurants in the world, they offered early access pre-reservation on-line which they then sent a link to confirm the reservation a few days in advance. I was very happy to get in as their closest competitor Don Carlo is closed...and I would have felt like I missed a quintessential experience. They are on a residential street which was swarming with people drinking champagne upon arrival: festive. Inside the restaurant was attractive with brick and dark wood. The Vermu (vermouth spritzer) was a bit weak. They served an empanada as the amuse bouche. I had the prime rib which was exceptionally tender and would have been enough for 2 people. I admit it is hard to give a steak house a 5 star rating. It was however the best restaurant on my trip to Buenos Aires and I am a foodie.More
