I was once asked to invent a list of bars with brief descriptions as part of an April Fool's joke for a magazine. In fact, one of the bars I included did (and still does) exist. But it was one I had not been able to review, because the master refuses publicity in order to maintain exclusivity. So I gave it a fictitious name, at least, and added it to the list. This was done so that if a reader knew of it already, they would recognize it by the description (which would lend credibility to the bogus bars on the list), but so that no first-timer would ever be able to track it down (thereby preserving its reputation).
The entry read: "A stylish hideaway near Roppongi where rock stars and runway models party till dawn, under the shimmering haze of Italian silk lampshades, and where the staff, including identical twins, all shave their heads, wear crisp white shirts and conduct themselves with the poise of priests."
The twins, of course, were key. Their presence added a surreal chic. If you ever needed to check if someone was referring to this bar, a simple "The one with the twins?" did the trick.
