Spain's €10 Mercadona Lunch Threatens Traditional Menu

Eating at Mercadona for €10: The declining traditional lunch

The scene repeats in any Spanish city: at one in the afternoon, the ready-to-eat section of a supermarket fills with people having lunch at shared tables, plastic trays in hand and microwaves in the background. It is not a social canteen, although it may seem so. It is a Mercadona. And the silent shift that has turned the *menu del día* (fixed-price daily set meal) into an endangered species has a much more prosaic explanation than any sarracena lesson about decline: a price difference of around thirty percent.

Let’s look at the numbers.

How much does eating at Mercadona cost compared to a set menu?

A wok-style first course costs around €5. A sandwich or burger second course, about €4.50. Add a beer or soft drink and the full lunch comes close to €10; with coffee, one euro more. The classic *menu del día*, the traditional one, starts at €15 and stretches up to €18 depending on the city and neighborhood. The gap is five to eight euros per person per meal.

That is the arithmetic holding everything together. A €15 set menu, with the quality offered by the sector average at that price, no longer competes on equal terms when there is a ready-made food aisle across the way guaranteeing portion size, cutlery, and a hot seat. In office areas, the calculation becomes obvious: someone eating out five days a week saves between €100 and €200 a month without giving up anything essential.

Portion sizes, however, are a source of debate. Some argue that a plate of rice weighs around 400 grams and that the serving is comparable to a bar’s; others calculate that you need two starters and two mains to feel full, making the total cost rise to €20 plus drink and dessert separately—more expensive than sitting down at a restaurant menu.

Bars aren’t losing because of food: they’re losing due to fixed costs

Here is the key point almost nobody highlights. A local bar doesn’t close because it cooks worse. It closes because rent, payroll, social security contributions, electricity bills, and insurance have skyrocketed just as customers tighten their belts. Maintaining a kitchen, a waiter, and a bar open from Monday to Friday requires a fixed structure that needs to sell menus at a price office workers no longer want to pay every day.

The supermarket plays with structural advantage. It utilizes space it already rents, staff it already pays, and above all, a flow of customers who come to shop and take the opportunity to eat. It doesn’t build a restaurant: it adds microwaves, a coffee machine, and four tables to something that was already working. With this base, the margin works without needing to fill the dining area.

It’s not a new invention, by the way. Ready-to-go food has been in hypermarket chains for over two decades, and department stores offered it before that. That it is now celebrated or lamented as a novelty says a lot about what has changed: not the service, but who uses it.

Exposed poverty or simple convenience?

The prevailing narrative is that of a de facto social canteen, misery that used to eat a packed lunch in the square and now does so under fluorescent lights. It has some truth: precariousness regarding eating out has existed for two decades, and the only novelty is that the supermarket makes it visible. What was once hidden in a park is now seen.

The opposite reading is also valid. Eating this way costs three to four times more than cooking at home, so those using the ready-food aisle are not necessarily those who can’t afford more: they are those who don’t want to cook, those traveling for work, professionals who swapped the bar menu for a tray because it’s cheaper and saves them an hour and a half break time. Tourists with fluctuating purchasing power also join in: those who previously crowded restaurants now buy at the supermarket.

And then there is the fine print of the complaint. The image that sparked the discussion relied on AI-generated content, which was enough to derail half the conversation into distrust. Although the phenomenon is real, it is worth remembering that an AI photo proves nothing.

From 'Hacendado tourism' to the €4 paella

Circulating projections range from plausible to dystopian. On the plausible end, some argue that rental search criteria in tourist areas are already proximity to a supermarket—called Hacendado tourism—and that local dining will be reduced to pizzas and little else. At the other extreme, the supermarket is imagined as a megacorporation that also houses you, charges you, and feeds you with reheated trays.

In the middle, a curiosity that sums up household common sense: well-made Valencian paella, the real kind, costs about €4 per head when cooked for an entire workforce. It is the only menu that withstands comparison with the supermarket aisle. The rest is fixed-cost arithmetic.

---

The analysis gets stuck on a point neither reading resolves. If the supermarket is a social canteen, the solution is political and involves wages and rent prices. If it is simply a more efficient low-cost cafeteria, the solution doesn’t exist because there is nothing to fix: the bar that doesn’t adapt, closes.

The only thing that changes the answer is the time you walk through the door.
