I have been to Mendoza before, but now coming back with a large group of friends. My driver / guide is suggesting the following places. They are different from the places I have been before, so curious what you know about them.
Finca Dagostino (lunch)
Finca la Anita (lunch)
I have previously visited, Alta Vista, Achaval-Ferrer, La Azul, Cuvelier los Andes, Vina Cobos, Catena, El Enemigo (also suggested for this trip), Altocedro (also suggested for this trip), Tapiz, Salentein, and others.
