But it wasn’t until the bar’s 13th anniversary in 2014 that Thompson felt compelled to pay special tribute to their somber opening day, after he heard a sobering statistic on the news that a “high percentage” of Americans would wake up 15 years to the day of the attacks and not remember the tragedy. “We don’t celebrate 9/11 that way, but when I heard those figures, I just thought you know, that’s kind of a tragedy,” he said. That’s when he decided to rename the lounge area, previously dubbed “Charlie Bar” after a former employee, after that fateful day. Bar 9Eleven also includes decor with a narrative timeline of Sept. 11 that compares Rio Mambo’s opening morning with the events in New York, Pennsylvania and in DC.
