The public house at the heart of the holographic Irish village of Fair Haven, kept by Michael Sullivan, where Voyager's crew drink, play games and mix with the townsfolk.
Sullivan's is the pub in Fair Haven, the nineteenth-century Irish village that Tom Paris creates on the holodeck. It is the natural gathering place for the crew when the programme is left running around the clock, with rings, arm wrestling and a good deal of stout.
In Fair Haven, Janeway takes an interest in the landlord, Michael Sullivan, and quietly rewrites his character, making him better read and removing his wife, before becoming uneasy at having a relationship with someone she can reprogramme. The pub is where much of their courtship takes place.
It returns in Spirit Folk, when regulars such as Seamus and Milo begin to notice the visitors' strange powers and the villagers come to suspect that they are dealing with spirits.
