If you have watched Musafir Cafe on Netflix, there's something quite interesting in it. It's a simple, sweet story following a couple that managed a cafe in the mountains.
The Musafir Cafe met the same traveller every time. They stopped for coffee on the way to somewhere else, aware from the start that this is a rest stop, not their awaited destination. Forgettable, almost by design.
But for the cafe owners, this was a real problem worth solving. If most visitors were only ever going to pass through once, the one thing worth engineering was making that single visit hard to leave behind. Something that the travellers could visit again or at least, pollinate its word amongst others.
Their answer was a small corner called the Promise Wall, where visitors wrote down a personal promise and pinned it up for anyone to see.
The mechanic borrows, whether by design or instinct, from what researchers call psychological ownership: a feeling that something is "mine," worth remembering, worth returning to. It's the same reason why lovers carve their names on historical sites.
Research in the restaurant industry points to three conditions that build it: a sense of belonging, a sense of identification with the place, and a sense of control over it.
The Promise Wall delivered all three in one small act. Writing the promise is a choice, so the guest keeps control. What they write becomes part of the café's fabric, visible to every visitor after them, which builds identification. Returning to find the note still there builds a sense of belonging.
A note pinned to that wall turned a rest stop into unfinished business. The traveller now had a reason to come back, if only to see whether it was still there, and every promise left by someone else became an invitation for the next traveller to add one of their own.
Spotify runs the same mechanic through personalised playlists, letting the listener build something that feels like theirs. IKEA runs it through assembly, handing the customer the last hour of the furniture's making. Different industries, same underlying move. Ownership is not given to a person. It is built by handing them a piece of the making.
Which raises the real question for a restaurant. How does the experience come to belong to the guest, not just please them? Something strong enough that they return, and strong enough that they pitch the restaurant to their own circle, unprompted. Marketing that the restaurant never has to pay for.
Don Norman's Emotional Design offers a useful lens here. People attach to objects through three routes: utility, uniqueness, and aesthetics. Something more practical than the alternatives. Something that feels uniquely theirs. Or something that looks like a genuine piece of art.
The ambience of a cute corner store, a fancy dining experience with exotic cuisines, or cocktails brewed like a true work of art. But an aesthetic designed by the restaurant still belongs to the restaurant. The guest is only admiring it.
What Musafir Cafe did was hand its aesthetic over. Anyone walking in saw a wall made of memories and promises left by travellers before them. The visible work of past guests became an invitation to add a layer of their own, and to become part of the aesthetic themselves.
Uniqueness works the same way, and it is often misread. It is not about what makes a restaurant different from its competitors. It is about whether the guest feels a connection to this visit that could not have happened anywhere else.
There is a cafe near our office. One afternoon, our team met there to sketch out what WHY Behaviour could become, all of it anchored on a single sheet of tissue paper from that cafe. The discussion was so enthralling and helpful for us that we almost turned superstitious about it. Every major discussion since — project planning, creative brainstorming — has landed back at that same table, again and again. And we kept making our notes on a single piece of tissue paper every time. It started with four people. A fifth joined. Then two more. And we plan to keep bringing more in the future.
Let's see how many minds here feel like being a behavioural scientist. You have to design for utility. What would you change in your restaurant if the goal was not just convenience but also attachment?
