I have eaten a prime rib at a resturant on the prime meridian, in Greenwich, England.
However, the greenwich prime meridian is not exactly on the prime meridian, due to an error Halley made many years ago. Many other counties, then said, why not us being prime. So nowadays, one has to specify the exact prime you are using.

But anyway, on Halley's prime, the restaurant was within walking distance of the Royal observatory, which according to western history, was used as the Prime Meridian by all British Navy Mapmakers for many years. But now according to British Law, it is now no longer on the Prime Meridian, the Prime is about 5 minutes East of there.
