The Restaurant has some of the most staggeringly extravagant decor ever seen, a variety of the strangest guests from throughout history, and serves a particularly fine Pan Galactic Gargle Blaster. Milliways is run by an incredible arrangement of life forms from everywhen, and is the one place anywhen that serves talking food. One of the waiters is called Garkbit.

Reservations are easily obtained, since they can be booked once the patron returns to his or her original time after their meal, and the restaurant's bill can be paid by depositing a penny in any bank account of the present time: by the end of the universe, the compound interest on that penny over the course of time after 170 quintillion years (short scale) will be enough to pay the extremely high bill. Near-instant transportation to the restaurant can be achieved in certain rarefied circumstances, such as being next to an exploding hyperspatial field generator on the planet where Milliways will eventually be built several billion years after the explosion occurs. Or have access to a Infinite Improbability Drive, such as The Heart of Gold.

The Restaurant at the End of the Universe is one of the most extraordinary ventures in the entire history of catering.

It is built on the fragmented remains of the ruined planet Magrathea, and is enclosed in a vast time bubble and projected forward in time to the precise moment of the End of the Universe. The end of the universe is an event that will take place almost one hundred and seventy quintillion (1.7x10²⁰) years in the future, in which the universe, or N-Space, collapses in on itself due to its being a closed system and entropy constantly building up. It is also known as the Heat Death of the Universe, Event Two, the Big Crunch, the End of Time, the Gnib Gnab, the Big Rip and the Blue Shift.

This is, of course, impossible.

In it, guests take their places at table and eat sumptuous meals whilst watching the whole of creation explode around them.

This is, of course, impossible.

You can arrive for any sitting you like without prior reservation because you can book retrospectively, as it were when you return to your own time.

This is, of course, impossible.

At the Restaurant you can meet and dine with a fascinating cross-section of the entire population of space and time.

This is, of course, impossible.

You can visit it as many times as you like and be sure of never meeting yourself, because of the embarrassment this usually causes.

This is, of course, impossible.

All you have to do is deposit one penny in a savings account in your own era, and when you arrive at the End of Time the operation of compound interest means that the fabulous cost of your meal has been paid for.

This is, of course, not merely impossible but clearly insane, which is why the advertising executives of the star system of Bastablon came up with this slogan: "If you've done six impossible things this morning, why not round it off with breakfast at Milliways, the Restaurant at the End of the Universe?"
