Sector XXXZ5QZX was an area of space, presumably a galactic sector. The Full name of this sector is XXXZ5 Quantum Plural Zed, Plural X-ray, also its name indicates it had Exotic Quantum plurality problems as well as Regular Quantum plurality problems (which is obvious because the Sector containing the bar at the end of the universe has too many temporal quantum plurality problems to mention here). This is evidenced by the fact that the Hitchhikers guide would keep saying goings on at this establishment and always following with "and this is of course impossible". Its most famous one was "You can reach this place before you arrive" So there where many Quantum Plurality problems with this location.
Also indicated with the XXX at the beginning This Sector is known for being the location of "The Evildrome Boozarama", which was a drinking establishment situated in a region of space known as Xaxrax Sigma. It sold a drink called the great Pan Galactic Gargle Blaster, costing seventy five dollars.
It was a former haunt of Ford Prefect and Hotblack Desiato. When they used to get hungry here, they would pose as health inspectors and go around confiscating people's meals and drinks until they got food poisoning.
