During the days of Prohibition in the 1930s, B. H. "Pat" O'Brien operated "Mr. O'Brien's Club Tipperary," one of many speakeasies in New Orleans, whose doors opened only to the select few who knew the passwords, "Storm's Brewin."  When the Prohibition Amendment was repealed in 1933, Mr. O'Brien moved his now legal drinking establishment across the street from the speakeasy to Pat O'Brien's original location in the600 block of St. Peter.  Today, Pat O's, famous for their "Hurricane" is located in Memphis, Orlando, San Antonio, and Cancun, Mexico.  Of course the New Orleans location still exists at 719 S. Peters.
