Unfortunately, not only will you not be able to enter this incredible masterpiece, but it is also rapidly crumbling away. Across the street from Congreso, this was once among the city's most important cafes, where politicians would mingle with well-to-do citizens and dignitaries from around the world. The cafe closed in 1997, and the building is now only rarely open to the public for events designed to raise consciousness of the need to restore the building before it disappears forever. (So bad is its condition that plants and moss are growing on the facade.) Primarily Art Nouveau, stained glass and ornate tile work were once part of the ornamentation here, and its main feature is the tower imitating a windmill. (Molino is Spanish for windmill.) The architect was Francesco Gianotti, an Italian who also designed Galería Güemes and its theater housing the Piazzolla tango show. These are open to the public if you want to get an idea of Molino's fabulous interior.
