The £285 Celery Stick: An Experiment in Hallucinated Credibility
Published on
The Most Expensive Vegetable in Mayfair
Last month, while the Silly Starfish was getting his new Eleventy-powered home, I found myself distracted by a question: How much absurdity can a polished UI actually mask?
It started with a simple technical curiosity. OpenAI had recently updated their image generation capabilities, and for the first time, the models were actually competent at rendering legible text. No more "gibberish-latin" menus; we were entering the era of the high-fidelity hallucination.
To test this, I decided to invent the most pretentious, unlikely culinary concept I could think of: Celery.
Not just celery as a side dish. Celery as a religion. A high-end, tasting-menu-only establishment in Mayfair where the humble stalk is elevated to an "architectural triumph."
The Hook: A Menu of Pure Fiber
I prompted the AI to generate a tasting menu. It didn't just give me food; it gave me pretension.
We’re talking about a £285 "Amuse-Bouche" of Celery Essence & Caviar, followed by an A5 Japanese Wagyu served with—you guessed it—smoked celery root purée. I even pushed it to include wine pairings that brought the total bill closer to the price of a used car.
I sent the screenshot to a few friends with a casual: "Thinking of booking this for our next catch-up? Looks a bit experimental but the reviews are insane."
The terrifying part? They bought it.
One friend started checking his calendar. Another commented on how "brave" it was for a chef to focus so exclusively on a single flavor profile. The AI hadn't just generated a menu; it had generated credibility.
Escalating the Absurdity
Once I realized how thin the line between "obvious joke" and "exclusive Mayfair pop-up" was, I couldn't stop. I did what any responsible researcher would do: I bought the domain celeryrestaurant.com.
I used an LLM to flesh out the "philosophy" of the restaurant—lots of words like restraint, obsession, and terroir. I generated photorealistic shots of minimalist dining rooms and close-ups of "Celery & White Chocolate Mille-Feuille" that looked disturbingly delicious.
The site looked better than half the real restaurant websites in London. I added mock 5-star reviews from The Times and the FT, and suddenly, I wasn't just hosting a joke; I was hosting a digital ghost that people were trying to haunt.
The Video Generation "Fail"
The final piece of the puzzle was video. I wanted a slick, cinematic "hero video" of a couple arriving at the restaurant to set the mood.
I turned to a simple video generation tool, expecting a 5-second clip of elegance. What I got instead was a masterclass in the "Uncanny Valley" of AI physics. No matter how I tweaked the prompt, the AI simply could not understand how humans interact with doors or each other.
In the best take—the one I eventually put live because it was too funny to delete—a classy couple approaches the entrance. The Maitre D' greets them with a stiff, algorithmic nod. Then, for reasons known only to the latent space, the man simply decides his journey ends there. He walks right off the frame, leaving his date standing alone. As she tries to enter the restaurant, the door just... closes on her.
It was a perfect, accidental metaphor for the whole project: a polished exterior that falls apart the moment you try to step inside.
The Reveal
I put the site live for April 1st. I added a booking engine that, after a few "processing" animations designed to build anticipation, popped up with a variety of "April Fools!" messages.
The stats were illuminating (and slightly worrying). A significant number of people tried to reserve a table for a £285 celery dinner.
It turns out that if you wrap a ridiculous idea in enough high-fidelity AI-generated assets, people will look right past the absurdity and start reaching for their wallets. It’s a reminder that as we move into a world where AI-generated media is indistinguishable from reality, the only thing keeping us grounded is our own skepticism.
And perhaps a healthy suspicion of any menu that charges thirty pounds for "Celery Essence."
Post-script: If you’re still craving celery, the site is still up at celeryrestaurant.com. Just don't expect the door to stay open for you.
