History and specifics
The decor of the restaurant was very old fashioned and reminiscent of 20th century restaurants, with wood paneling, white tablecloths and framed pictures of baseball legends. There was also a stuffed alligator hanging from the ceiling of the restaurant. Joseph would often tell his grandson Jake Sisko that the alligator was in stasis, and at night the alligator would be released from stasis to guard the establishment. (DS9 episodes: "Homefront", "Paradise Lost")
Sisko's was famous on Earth for its Shrimp Creole and its Gumbo, but the restaurant also became famous for providing meals that people couldn't find anywhere else on Earth. When Nog entered Starfleet Academy in 2372, the Ferengi found it difficult to find tube grubs anywhere on Earth, and soon discovered that Joseph would prepare them for him. (DS9 episode: "Homefront")
As well as being a restaurant and business, Joseph had always regarded his customers as an extension of his family, and has often included them in family celebrations. Shortly after the birth of Joseph's first son, Benjamin Sisko in 2332, Joseph was known to show off the newborn with one arm, while serving tables with the other. (STA novel: Maker)
In an alternate timeline in which Benjamin Sisko was trapped in a subspace field in 2372, Jake and Azeni Korena were married in Sisko's at Joseph's insistence. The wedding guests included Kira Nerys, Jadzia Dax and Miles O'Brien. The restaurant was still called "Sisko's" in the mid 25th century. (DS9 episode: "The Visitor")
