The Elfsong Tavern was a well-known tavern in the city of Baldur's Gate.
The two-story building was large and elegantly built, albeit somewhat dilapidated. The ground floor was the taproom featuring the bar and a large number of tables and dark, anonymous booths. One of the more notable decorations was a stuffed baby beholder mounted over the bar. The only lighting was provided by many blue driftglobes, which floated about near the ceiling. The furniture was stout wood marked by any number of nicks and slashes from swords and knives. Individual tables were cordoned off with hanging tapestries that provided visual (but not vocal) privacy. The upper floor was filled with private meeting rooms, which could be rented either by the candle—the time it took a short taper to burn down—or by the evening.
The name derived from an unusual haunting: a ghostly female elven voice heard periodically throughout the establishment. The singing was quiet, but could be heard quite clearly. It was most often described as both beautiful and mournful. The identity of the singer was unknown, but it was clear that her song was a lament for a lover lost at sea. No other music was permitted inside the Elfsong.
There is a small cellar and a long forgotten Teleportation Circle there that the party used once on the way to Chult.
