When the Brooklyn Bridge first blocked Water Street from sunlight in 1883, this bar/restaurant had already been serving the local population for almost a century - in more ways than one. An 1860 NYC census lists 279 Water Street as the home of six Irish prostitutes. According to a NY Times article, the Bridge Cafe has been a "drinking establishment" since 1847, thus making it the oldest continually running bar in NYC. Only a few blocks from the South Street Seaport, it is decidedly not a tourist trap, after all, Ed Koch held court here twice a week at his private table during his mayorship
In the early days the customers were dock workers, prostitutes and their 'friends', and assorted low life. Nowadays, the very good food and convivial atmosphere attracts locals, financial types (if there's any left who can afford a meal after the toxic debit farrago), politicians and tourists.
I'd give the pickled walnuts on sale from jars on the bar a miss if I were you.
