HAVANA -- It's happy hour again at the original Sloppy Joe's saloon, an iconic Cuban bar that reopened Friday after a nearly 50-year hiatus and is sure to quickly become a must-see for tourists eager to drink in the flavor of Havana's freewheeling past.Waiters in black and orange shirts and ties shook up round after round of the Sloppy Joe cocktail, a cool, refreshing blend of brandy, port and Cointreau, with a fruity pineapple finish, while about two dozen customers took a break from the spring heat and noshed on ceviche and marinated shrimp."Finally the big day, after so much waiting, and I think it's been worth the pain," said Ernesto Iznaga, manager of the reborn Joe's. "May all our clients ... upon entering, breathe in that '50s atmosphere that characterized the place."Historic pictures lining columns in the bar bring that era to life most vividly and are keen reminders of how Sloppy Joe's was one of the most popular places among American tourists who made Havana, just 90 miles from Florida, their party-time playground as far back as Prohibition.One photo shows Ernest Hemingway, Noel Coward and Sir Alec Guinness when the latter was in town to film Our Man In Havana, which included a scene shot in the bar. On Friday, the movie was showing on twin flat-screen TVs above the bar."Everybody had to have their picture taken at Sloppy Joe's, whether they were basic American tourists or movie stars," said Barbara Bachman, a New York book designer who was one of the first to belly up to the bar for a drink.Bachman, who was on her annual trip to the island to visit family with her Cuban-born husband, said she learned about the bar from photos she found at Havana flea markets. She asked around and finally tracked it down several years ago. She said it was just a bunch of dust and a few sticks of furniture.The bar was shuttered in 1965 as Fidel Castro's Communist government nationalized nearly all private enterprise, and it was later abandoned to decay over the decades until a government agency began looking at restoring it in 2007.
