A product of Timoricorian ( Time Lord) technology, not much is known about this exact model of TARDIS, only that it was an experimental model that was never put into mass production by the Time Lords. The reason for this, like the exact origins of the Cantina itself, are unknown. The Cantina's apparent default setting seems to be that of a 21st Century restaurant from Sol 3, causing speculation which suggests that the Time Lord who designed the vessel had a fetish for the current human-built structures of Sol 3, also known as Earth.
