Alcotraz holds a 4.8 and this holds a 4.3, and the difference is entirely the sample and the promise
Jailhouse Bar holds a 4.3 from sixteen reviews, which is not a rating and which we will not use.
But it is the second prison-themed bar in this district, and the comparison is instructive.
The other one
Alcotraz holds a 4.8 from two thousand seven hundred and ninety-five people.
You smuggle a bottle in. Actors shout at you. You are put in a cell.
And it is one of the highest-rated venues in Shoreditch, and we have spent six hundred and forty articles being rude about themed venues before being comprehensively corrected by the numbers.
Why Alcotraz works
Because it promises an activity rather than an experience.
And that distinction is the single most useful thing this survey has produced about themed venues.
An experience cannot be delivered on demand. A speakeasy promises that the evening will be memorable, and a wet Tuesday will not cooperate, and the customer is left measuring the night against a standard the venue invented.
An activity can be delivered. Every time.
Alcotraz promises: you will smuggle a bottle past an actor, you will be shouted at, you will sit in a cell, and somebody will mix your spirit into a drink.
That is completely achievable. It happens exactly as described. The gap between expectation and delivery is approximately zero.
Clays: 4.9. Hijingo: 4.7. Bat and Ball: 4.8. Shuffle Club: 4.4.
The activity bars hold, every single time.
The sixteen reviews
Which is why we cannot tell you anything about this one.
Sixteen is the deepest part of the dead zone. Two bad nights would put it below 4.0. Two good ones would put it above 4.6.
It is not a rating. It is a handful of evenings, and it is being displayed to you in the same font, on the same scale, as a 4.8 from two thousand seven hundred people.
With the review count underneath, in grey, smaller.
They know exactly what they are doing.
The trap
A venue with sixteen reviews does not appear in a search. A venue that does not appear in a search receives no customers. A venue with no customers generates no reviews.
The loop closes fast, and once a London venue has been open six months in the dead zone, its statistical probability of climbing out is small.
Verdict
Sixteen reviews. Unknowable.
Go, be the seventeenth, and be the reason it escapes.
Immersive theatre, briefly
Because both of these venues belong to a genre that has become an enormous industry in this city, and the people in it deserve a line.
The performers are actors. It is a job, and it is a hard one, and they are doing four sittings a night in character with no script and forty drunk people improvising at them.
The Prat’s theatrical desk would gently note that the person shouting at you in a prison guard’s uniform has very probably had proper training, is between other work, and is being paid less than the person who poured your drink.
Be decent to them. They are the product.
