Atop a federal landmark building in New York City’s South Bronx, there is a little slice of Havana, with a trio of commercial folding glass doors maximizing the skyline views. Zona de Cuba is a pulsating indoor-outdoor party with a killer view above the East River, clear over the island of Manhattan. It is also one of the first rooftop restaurants in its immediate area. The entire width of the establishment enjoys a sky-line view through full-height collapsible glass walls by NanaWall Systems. The opened wall erases any division between the indoor dining room and the outdoor deck with its colorful Caribbean decor, helping Zona de Cuba serve up authentic island atmosphere within the concrete jungle of New York.
