Quick Market Study: Go / No-Go
Before investing tens of thousands of euros in a lease or a concept, 3 indicators are enough to make the call:
- Is local demand sufficient? (foot traffic + purchasing power)
- Does the competition leave room? (saturation or a niche to take)
- Do the unit economics work? (average ticket, food cost, margin, covers/day needed to reach break-even).
👉 Quick rule: if your rent exceeds 10% of forecast revenue, or if your break-even point is above 80 covers/day in a neighborhood with average foot traffic, be careful.
Why a Market Study Is Essential
A market study is not just a bank file: it is a compass.
It is used to:
- Measure the real size of the accessible market.
- Validate the relevance of the concept and its pricing.
- Identify risks before committing cash.
- Convince investors and banks.
Expected deliverables: summary note, catchment area map, price/offer benchmark, revenue forecast & P&L, 90-day action plan.
📍 Catchment Area and Foot Traffic
- Isochrones: calculate the area reachable within 5/10/15 minutes on foot, by bike, by public transport.
- Traffic generators: offices, schools, train stations, gyms, hotels.
- Moments of truth: lunch peak (12-2 pm), evening (7-9 pm), weekend vs. weekday.
👉 Simple field test: count passersby over 3 time slots (morning, noon, evening) for 3 days (Tue, Thu, Sat). Then estimate your target conversion rate (e.g. 1 customer for every 50 passersby).
🎯 Customers and Dining Occasions
Typical Personas:
- Busy professionals (quick lunch, budget ≤ €15).
- Families (evenings & weekends, the experience matters).
- Students (low psychological price point, high share of delivery).
- Tourists/foodies (looking for authenticity, higher budget).
👉 Each persona is tied to a “mission” (eat fast, celebrate, treat yourself, order takeout). Your concept must clearly cover at least one.
🥘 Competition and Positioning
- Mapping: direct competitors (same cuisine) & indirect ones (snack spots, dark kitchens).
- Benchmark: prices, reviews, strengths/weaknesses.
- Winning positioning: a clear, differentiating promise (e.g. speed, a rare specialty, healthy, immersive experience).

💶 Menu, Pricing & Profitability: Menu Engineering
Optimize your menu based on volumes sold, margins and product pairings (what customers buy together).
With Fullsoon:
- Automatic detection of pairs/groups frequently ordered together (e.g. Main A + Drink B + Dessert C).
- Suggestions for bundles/menus to test: name, composition, recommended price, placement on the menu.
- Tracking of uptake rate, average basket and food cost so you can iterate quickly.
| Category | Definition | Recommended action |
|---|
| ⭐ Stars | High margin + high sales | Showcase (top of the menu, server recommendation, visuals) |
| 🐴 Plow-horses | Low margin + high sales | Optimize cost/price (recipe, portion size, bundle, slight price increase) |
| 🧩 Puzzles | High margin + low sales | Boost visibility (showcasing, renaming, discovery offer) |
| 🐶 Dogs | Low margin + low sales | Remove or rework (recipe/price), otherwise drop from the menu |
🧠 Psychological pricing Use price thresholds (€9.90 / €14.90 / €19.90) to maximize perceived value. 📏 Elasticity Test sizes, set menus & combos to find the best volume × margin balance. 🎯 Anchoring Add a slightly pricier signature dish to make the rest of the menu look better by contrast.
📈 Break-Even Point and Business Model
The first step is to calculate the break-even point. This is the point from which every cover generates profit. The formula is simple:
Break-even = Fixed costs / (1 – COGS% – Payroll%)
Let's take an example. With €20,000 of fixed costs per month, a food cost of 30% and payroll of 35%, the restaurant will need to reach about €54,000 in monthly revenue. In practical terms, with an average ticket of €20, that equals about 90 covers per day. This figure must be tested against the reality of the neighborhood: is it realistic given foot traffic and competition? If the answer is no, it is better to adjust the concept or change location before investing.
COGS (CMV in French): “cost of goods sold” = the food cost actually consumed to produce what was sold over a period.
Formula: COGS = Opening stock + Purchases − Closing stock; Food cost % = COGS / food sales excl. VAT.
COGS does not include wages, rent, energy, marketing, etc.
🧪 Testing the Market in the Field
Numbers are not enough; they must be tested against reality. A field survey, even a simple one, brings valuable data. A quick poll of 100 to 200 people (via Google Forms shared by QR code, or through a small geotargeted ad campaign) lets you measure interest and willingness to pay.
In parallel, qualitative interviews add depth: ask potential customers about their habits, host a test evening or even open a temporary dark kitchen to observe real sales. The right indicators to follow are concrete: how many people scan a flyer? How many place an order with a promo code? What average basket comes out of this first test?
📊 Indicators to Monitor Continuously
Once the restaurant is open, the key is to track the right indicators so you can adjust course. On the demand side, we look at covers per day, occupancy rate and loyalty. On the economics side, average ticket, food cost and gross margin per dish remain essential. Daily operations are measured by the number of stockouts, kilos of waste produced or waiting times in the dining room. Finally, online reputation plays a central role: the trend in your Google or Deliveroo rating, and above all the themes that recur in reviews, provide an instant barometer of customer satisfaction.
🛑 Anticipating Risks Before They Become Traps
Like any project, a restaurant can fail for the wrong reasons. The most common is market oversaturation: opening yet another pizzeria in an already crowded neighborhood dooms the project from the start, unless you offer strong differentiation. Excessive dependence on delivery is another risk: commissions eat into margin and weaken the model. As for rent, it can become a millstone if the lease exceeds 10% of forecast revenue. Finally, the scarcity of skilled staff means you need to design a simple operating model, with well-mastered recipes and fast in-house training

Frequently Asked Questions About Restaurant Market Studies
Frequently Asked Questions
Why do a market study before opening a restaurant?
A market study lets you measure real demand, assess the competition and check the project's profitability before committing expenses. It is the best way to reduce risk and convince banks and investors.
What are the key elements to analyze in a restaurant market study?
The essential points are: the catchment area and its foot traffic, customer profiles, direct and indirect competition, price positioning, and the break-even calculation. The analysis should combine hard figures with field observations.
How do you calculate a restaurant's break-even point?
The formula is: Fixed costs / (1 – COGS% – Payroll%). Example: with €20,000 of fixed costs, a food cost of 30% and payroll of 35%, you need to generate about €54,000 in monthly revenue, or 90 covers per day with an average ticket of €20.
How do you gather future customers' opinions before opening?
You can hand out a paper or online questionnaire (QR code, social media), interview passersby directly, or run a full-scale test through a pop-up restaurant or a temporary dark kitchen. The data collected is used to fine-tune the concept.
Can artificial intelligence help make a market study more reliable?
Yes. Solutions like Fullsoon forecast the number of covers and the dishes expected based on weather, events and history. They reduce waste, optimize purchasing and can gain you up to 8% gross margin and 20 hours/month of management time.
What are the main risks to anticipate?
Common pitfalls are: oversaturation of the local market, excessive rent, overreliance on delivery platforms and difficulty recruiting staff. Anticipating and quantifying them is an integral part of the market study.
