Racing slang for a horse with no public form, and the whole point is that the information is missing
Darkhorse holds a 4.6 from six hundred and eighty-five reviews, charges twenty to thirty pounds, and the phrase in the name is about missing information.
A dark horse
Which is racing slang, and it is quite precise.
A dark horse is one whose form is not known.
It has not run in public, or not enough. The punters cannot assess it. The bookmakers cannot price it properly.
It is dark in the sense of being unlit – not sinister, not secretive. Simply not visible.
And that is worth money
Which is the whole of it.
Because a stable that knows its horse is very good, and has been careful not to let anybody else find out, is holding an asymmetry of information – and it can back it at a long price.
The odds reflect what the public knows. And the public knows nothing.
So the value is not in the horse. It is in the gap between what the horse is and what everybody thinks it is.
Which is precisely this survey
Eight postcodes and thirteen hundred and two articles.
The star rating measures the gap between what somebody expected when they pushed the door and what they got.
And the venues that win are the ones nobody had heard of – the small, cheap, unadvertised rooms with no story and no rope, which are underpriced by the market and which people walk into with no expectations at all.
And then they are good. And the gap inverts.
A dark horse and a cheap pub are the same trade.
And a favourite cannot win this way
Which is the corollary, and it is why the expensive rooms struggle.
Because a venue that has been reviewed, and photographed, and puffed, and priced at seventy pounds a head has told everybody exactly what to expect.
It has published its own form.
And now it must meet it, every night, in front of people who arrived certain.
The safest way to a good rating is to promise less.
GONG, on the fifty-second floor of the Shard, holds a 4.1. A canteen in a hospital beat it.
Verdict
And it is why we refuse the perfect scores
Because a venue with no form cannot be assessed, and a 5.0 from twenty people is exactly a dark horse – unpriced, untested, and unknowable.
The Bootlegger, Covent Garden: a perfect 5.0 from twenty-two people.
The Bootlegger, City of London: a 4.3 from five hundred and twenty-six.
Same chain. Same fit-out. Same bar.
The 5.0 was not better. It had less evidence.
And a horse that has never run is not a fast horse. It is a horse nobody has timed.
The number is not a report card. It is a measure of how much has happened to you – and six hundred and eighty-five people is a real sample, and it means this venue has already run in public and the time was good.
Verdict
Excellent, strong number – and it will not stay dark.
