Awasi Atacama,Explora & Mare Australis Trip

We have had a truly wonderful vacation so far. (I told Audrey it shows the wisdom of spending a lot of money quickly.) Awasi, Explora and Australis were each exceptional in their way. And your arrangements have been excellent - we have especially appreciated the quality guides. I have some really terrific photos so far. We had some excitement today as our original flight from Ushuaia to BA was significantly delayed. But the airline graciously switched us to LAN so we made the connection to Iguazu. What is your recommendation for our last night's dinner in BA? Is there a high-end romantic place you would recommend? Maybe steak for the sake of tradition or perhaps we should do steak on the night before? (In case I didn't mention it, Kaupe was very enjoyable. The owners are quite gracious.) d
