Before the Cuban revolution, La ?poca was a major department store on the island. Although it still occupies a physical location in central Havana (as a dollar store of all things), the brand -- along with much of the essence of Cuba -- made the trip across the straits and settled in downtown Miami on NE Second Avenue. For 40 years, el exilio flocked to the packed store, even after the shopping district lost much of its vibrancy. This past December, though, La ?poca moved over to the old Walgreen's location on Flagler. Many will remember the 1936 Streamline Moderne structure as the site of a popular cafeteria; however, now the contents of La ?poca are spread across three of the exquisite building's five floors. The increase in elbow room is certainly welcome, but more important, this underscores that the downtown resurgence isn't a pipe dream.
