Katie's Bar in Smithtown is reportedly haunted, with alleged paranormal activity including flying objects, unexplained footsteps, sudden chills, and apparitions. Some sources suggest the hauntings are related to its history as a Prohibition-era speakeasy and a man named Charlie Klein, who was a bartender and bootlegger before dying by suicide on the premises. The basement area is considered particularly active, though a friendly presence called "Charlie" is sometimes reported there, while the upstairs is said to have more mischievous ghosts. Orbs, distorted faces in mirrors, and transparent children appearing in photos have been reported. Unexplained footsteps and voices in empty rooms are common. Guests have experienced sudden chills and feeling watched by unseen presences. Reports include flying wine glasses, a floating soda gun, and other objects moving on their own.
