For the type of person, please see night owl.
The Night Owl was a little coffee shop on Market Street in San Francisco. It was frequented by Kathryn Janeway.
In 2375, after establishing relations with the Species 8472 aboard Terrasphere 8, Janeway asked "Boothby" whether they had included the Night Owl in their recreation. Boothby replied that they had not. (VOY: "In the Flesh")
