On the second floor of the Port Authority Bus Terminal is a lone Irish bar called McAnn’s. It has no bathroom and its regulars drink in the absence of sunlight. It has existed behind a blur of miserable commuters for 20 years, and it is the last location of a forgotten chain of New York bars founded in 1945.

The wall clock at McAnn’s is set seven minutes fast to keep customers on their toes about bus schedules. Bartenders stash beer cans into brown paper bags for commuters in a rush. As to being a bar without a bathroom: customers must exit McAnn’s to use Port Authority’s public restrooms — a temporarily sobering experience for the tipsy who instantly find themselves surrounded by crowds and fluorescent light.
