Why single-product foodservice will appeal to consumers in 2025: marketing, psychology and the impact on multi-site catering.

The illusion of choice and the quest for simplicity: when supply saturation pushes towards hyper-specialization

"Too much choice kills choice". This paradox, studied for decades in behavioral psychology, is today a key lever for the success of mono-product concepts.

In the organized catering sector, where consumption is marked by hyper-abundance, customers and diners are looking for offers that simplify their decision-making.

Sheena Iyengar and Mark Lepper's 2000 study at Columbia University is a key reference in behavioral psychology on the impact of too much choice on consumer decision-making.

The researchers conducted an experiment in a supermarket, where they set up a tasting stand offering jams. Two scenarios were tested:

• A stand with 24 varieties of jam
• A stand with just 6 varieties

The results revealed a particularly striking dissonance:

• More customers stopped in front of the stand with 24 choices (60% of passers-by versus 40% for the one with 6 choices)
• But those exposed to the 6 choices bought much more: 30% of them bought a jam, compared with just 3% for the 24-option stand
• Customers with too many choices also declared themselves less satisfied with their selection, showing a phenomenon of post-choice regret

This phenomenon is known today as the choice paradox (or Choice Overload). The more options a consumer is faced with, the more:

• His decision-making process is long and stressful (cognitive fatigue)
• He's likely to avoid the decision (hesitation = purchase abandonment)
• His level of satisfaction decreases, as he fears having made the wrong choice

Single-product restaurant concepts exploit precisely this cognitive bias:

• Ultra-simplified cards = quick decision-making
• Less choice = more perceived satisfaction
• A single, mastered offering = fewer doubts about quality

Example: A brand specializing in a single product (e.g. burgers, ramen, eggs...) reduces the mental load on consumers, who know exactly what they've come for. As a result, they're more likely to order quickly and return, convinced they've made a good choice.

.

In organized foodservice, each chain will thus be able to engage in strategic thinking from 3 angles:

• How to reduce consumer decision fatigue when faced with restaurant menus that are sometimes too long. When too many options are available, customers can experience a form of cognitive lassitude, which lengthens their decision-making time and can even generate post-choice dissatisfaction. Studies in neuroscience applied to catering show that reducing the number of choices to an optimal number (5 to 7 main courses, for example) improves order speed and customer satisfaction.
• How to respond to the growing need for clear, identifiable cues when taking an order. In a context where information overload is omnipresent, consumers are looking to be guided by simple, strong signals. A mono-product concept allows for better brand memorization and immediate recognition, which facilitates the act of purchasing. This decision-making principle is well known in food branding: specialization reinforces differentiation.
• How a retailer can attract consumers by reducing cognitive friction and reassuring them with a clear, simple offer. A menu centered on a flagship product (burger, Neapolitan pizza, fresh noodles...) enables customers to immediately project themselves onto their consumption experience. This is particularly effective for multi-site chains that need to ensure consistency of service and perception between their different locations.

Perceived expertise: specialization as a guarantee of quality

Monoproduct specialization also appeals in commercial and institutional catering because it's part of a logic of excellence. By concentrating their efforts on a single type of dish, these chains project an image of absolute mastery.

Take Big Fernand in France, for example, which has built its success on the promise of the "gourmet French hamburger". Internationally, concepts such as Ichiran Ramen (personalized ramen) in Japan or Eggslut (eggs in all their forms) in the United States show that specialization reinforces culinary credibility and attracts a clientele in search of authenticity.

Specialization is the key to success.

Why does this perception work?

• A focus on a single product implies more controlled sourcing and production
• Communication is simplified and immediately identifiable
• The customer instinctively associates mono-product and expertise, reducing his level of uncertainty about the quality of the experience

The viral effect and the impact of social networks on the success of the mono-product

The emergence of social platforms like Instagram and TikTok has radically transformed the restaurant landscape. The mono-product is cut out for these new digital uses:

• An easily identifiable and memorable concept
• A strong visual aesthetic that fuels viral trends
• A mechanic of rarity and exclusivity that generates FOMO (Fear Of Missing Out) among consumers

Furthermore, the "food porn" effect has accelerated the success of numerous concepts, such as Pasta Evangelists (fresh artisan pasta on delivery) or 100% avocado toast chains. Relying on a single product but staged in a thousand different ways, these brands transform their dishes into veritable viral icons.

Adoria use case: Several fast-food chains have integrated forecasts based on social trends into their inventory management. Thanks to real-time data analysis, these chains adjust their single-product offers according to the virality observed on digital platforms.

Operational challenges: optimized management, but risky dependence

While single-product concepts seem to have everything going for them, they also pose specific management challenges, particularly for multi-site restaurateurs.

The advantages can be as follows:

• Purchasing optimization: by focusing on a limited number of products, it's easier to negotiate prices and reduce losses
.
• Standardization of production: team training is faster, service smoother
• Better cost control: sales predictability improves margin management.

With sometimes certain risks to take into account:

• Dependence on a single trend: if the product becomes obsolete, the whole concept collapses
• Difficulty in adapting to changes in demand: impossible to pivot easily
• Logistical pressure on supply:an out-of-stock situation can bring the whole business to a standstill
.

Adoria use case: Chains with a mono-product strategy use Adoria to optimize their order flows and limit the risks of overstocking or out-of-stock situations. Forecasting sales volumes enables them to anticipate stock rotation and adjust purchases accordingly.

In a model where every operational detail directly impacts profitability, single-product concepts require fine-tuned management of purchasing, inventory and product profitability. Adoria, with its Purchasing and Ordering module, enables multi-site restaurateurs to optimize the entire procurement process, from supplier selection to order management and material cost analysis.

• Purchasing optimization:by centralizing orders and integrating real-time alerts on out-of-stock situations and price variations, Adoria enables single-product retailers to secure their supplies and maintain consistent quality.
• Margin management: thanks to integrated profitability analyses, chains can dynamically adjust their selling prices in line with fluctuations in raw material costs, guaranteeing an optimized pricing strategy without compromising their competitive positioning.
• Multi-site synchronization: Adoria facilitates the implementation of an operational standard, enabling chains to ensure a homogeneous customer experience across multiple outlets, while adapting the offer to suit local specificities.

Case in point:The Pokawa brand, leader in poke-based bowls, has expanded rapidly in France and internationally. With over 100 outlets, it chose Adoria to structure and pilot its growth. Thanks to the platform, Pokawa has been able to rationalize its purchasing, better manage its suppliers and optimize its material costs, guaranteeing perfect control of its single-product concept while ensuring consistent quality in all its establishments. By adopting an integrated back-office solution, Pokawa was able to gain greater efficiency and visibility over its overall performance, supporting its large-scale development.
