The Ox and Lamb was a little inn in the holographic 19th century Irish village Fair Haven. A sign hung over the entrance read Fáilte, or "Welcome" in the Irish language.
In 2376, the owner of the Ox and Lamb shared some recipes with Neelix. Neelix later planned to prepare a traditional Irish meal here, but couldn't decide between blood pudding, mutton, and creamed cabbage. Chakotay planned to meet Neelix at the Ox and Lamb, and ran into Captain Kathryn Janeway and Michael Sullivan on his way in. (VOY: "Fair Haven")
Later, Neelix took over the Ox and Lamb, with steamed cabbage on his menu. Harry Kim also asked Maggie O'Halloran for a walk at the Ox and Lamb. (VOY: "Spirit Folk").
The style of name is typcal of english inns but not irish pubs , but that may be an error on Tom's part
