NEW ORLEANS – It is approaching happy hour, which is any waking hour on Bourbon Street, the jazz bellowing from street musicians as tourists sip daiquiris from plastic contraptions. Even on a windy midweek afternoon, this area is a kaleidoscope of beads, booze and beignets. Bars advertise that hangovers are installed — and repaired. A faded cover of the Times-Picayune hangs on the wall at Finnegan’s Easy with the headline screaming “AMEN!” in celebration of the New Orleans Saints’ lone Super Bowl victory.
