In a charming and creative space that was once a private residence in Belgrano, chef Martín Molteni's dining room offers up a tribute to the lesser-known products of the region. Specializing in unusual meats—llama, wild boar, rabbit, and quail are regular offerings—as well as fresh fish, unusual grains and vegetables, and hand-crafted cheeses, Molteni brings his overseas training in France and Australia to bear on his Argentine heritage. The menu changes completely every two or three months to reflect the freshest seasonal ingredients. While the menu doesn't list vegetarian options, give advance notice when you reserve and the kitchen will turn out equally stunning vegetable plates. A chef's tasting menu is also available.
