We had just returned from a long trek and had one last night in Cusco.  This restaurant cam highly recommended and so we figured we would try it out.  I had not yet had alpaca and wanted to try it.  I am no alpaca expert, but theirs seemed perfectly prepared to me.  It was absolutely delicious.  We also sampled several S. American wines (I did a tasting flight so I tried 4 different wines for the cost of one glass).  The wines were really delicious. I wish I had written down the names of the vineyards!  Cozy atmosphere and delicious food, just perfect for a chilly Andean night.
