Best restaurants for a Croque Madame in Buenos Aires

North Americans, Aussies and Brits that favor an egg or two on the breakfast plate, can take comfort in the fact that many restaurants, boulangeries and cafes in Buenos Aires, that open early for the coffee and croissant crowd, have the classic French Croque Madame on the menu. It's a grilled cheese sandwich, topped with an egg, either fried or poached. In fact, this is one of the most readily available egg dishes for breakfast being offered by three chain-restaurants that open early.
