P.J. Clarke's (1884)
P.J. Clarke's is like any other classic Irish tavern in New York. During the prohibition they did not close and instead made bathtub gin and smuggled in Scotch from Canada. The owners changed many times until it closed down. In 2002 it was re-bought and is now back, revamped, and better than ever - without losing its old school vibe.
