We went to this place three times to eat. Great meat and excellent fish. There is also a salad bar available and a tenedor libre menu that is super cheap -- US$6 or so for all you can eat. Even with the tenedor libre menu, Moustaccio stays formal enough to make for a bit of a romantic meal. If you like fish, don't miss the Basque-style Corvina they do there called Corvina Moustaccio – it’s a hefty filet is oven roasted with onions, peppers, white wine and bay leaves. Fantastic. I've been trying to duplicate it for months. And the Corvina Moustaccio is one of the most expensive items on the menu, coming in at about AR$15.
