McSorley's Old Ale House in Manhattan's East Village has been open since 1854. The oldest saloon in New York has been standing for 170 years, serving a few beers and burgers.

The secret of the pub? “Keep the beer flowing and leave the door open,” sums up its boss Teresa Maher. The pub is only three kilometers from the site of the World Trade Center, whose two twin towers were destroyed by planes rushed by the jihadist group Al-Qaeda on September 11.
