The Tempus Fugit was a restaurant on Pella Satyrnis owned by the Fifth Doctor. The Doctor created it in order to attract Alexhendri Lassiter's attention after he was thrown out of the Crystal Bucephalus restaurant, reasoning that attracting the Bucephalus was the only way he could get back to it. When he was finally rescued, the Doctor gave ownership of the restaurant to his assistant manager, Raphael, with instructions that the Benefactors' Booth would always be available for the descendants of the family who helped him after he arrived on the planet.

The Sixth Doctor contemplated returning to the Tempus Fugit after he accidentally escalated a civil war on the planet Maradnias, but decided that he didn't want to face what his makeshift family on Pella Satyrnis would think of his actions. (PROSE: The Quantum Archangel)
There was also a concession of the same name in the Food Court at the Frenko Bazaar. It was active when the bazaar was visited by the Second Doctor, Jamie McCrimmon and Zoe Heriot. (COMIC: Bazaar Adventures)
