Last month, a bistro owner showed me his 4.9-star Google reviews while closing his doors permanently. He'd given customers everything they wanted – extra portions, premium ingredients, free appetizers. But those perfect reviews couldn't save him from bankruptcy.
What review sites do see
Review sites and customers judge you on what they experience:
- Taste: Is the food delicious?
- Presentation: Does it look beautiful?
- Service: Friendly and fast staff?
- Atmosphere: Cozy decor and music?
- Value for money: Do you get what you pay for?
These factors drive customer satisfaction. But they reveal nothing about your actual profit margins.
💡 Example:
Restaurant A gets 4.8 stars on Google. Guests love the generous portions and fresh ingredients.
- Steak 300 grams instead of 200 grams: +€4.80 costs
- Only premium brand ingredients: +€2.20 per dish
- Free bread before meal: +€1.50 per table
Result: High reviews, but food cost of 42%
What review sites don't see
Behind those glowing reviews, a different reality unfolds:
- Food cost percentage: How much of your revenue goes to ingredients?
- Waste: How much food gets thrown away?
- Portion size: Are you giving too much for the price?
- Purchasing strategy: Are you overpaying for ingredients?
- Menu composition: Are you mainly selling expensive dishes with low margins?
⚠️ Note:
A restaurant with excellent reviews can lose thousands of euros every month due to high food costs. Customers will never know or mention this in reviews.
The hidden costs of perfection
Many restaurant owners chase perfect reviews. That leads to choices that delight guests but destroy your profit. Most kitchen managers discover this painful truth too late: every "generous" decision adds up fast.
💡 Example: The perfectionist
A bistro wants 5 stars and does everything for guests:
- Extra large portions: food cost rises from 30% to 38%
- Free amuses and bread: +€3.50 per table
- Only fresh fish (no frozen): +€4.20 per dish
- Always say yes to special requests
Reviews: 4.9 stars. Profit: -€2,400 per month
Why profitability isn't judged
There are logical reasons why guests and review sites don't judge your profit:
- No insight: Guests don't know what ingredients cost
- Not relevant: For guests, only their experience matters
- Invisible: Financial problems aren't visible in the food
- No expertise: Reviewers aren't business consultants
Guests pay for an experience, not for your profit margin. They expect quality for their money, but don't need to know what it costs you.
The danger of review-driven decisions
Making decisions purely based on what brings good reviews can be dangerous:
💡 Example: The review trap
A restaurant reads: "Portions are a bit small for the price." They decide to make all portions 25% larger.
- Reviews improve from 4.2 to 4.6 stars
- Food cost rises from 32% to 40%
- Monthly profit drops by €4,200
Better reviews, but the business goes bankrupt
Finding the balance
The goal isn't to ignore reviews, but to find balance between guest satisfaction and profitability:
- Measure your food cost: Know what each dish costs you
- Set boundaries: Not every complaint needs to lead to change
- Focus on efficiency: Better purchasing instead of larger portions
- Communicate value: Explain why your prices are fair
⚠️ Note:
A restaurant that goes bankrupt due to high costs helps no one - not the owner, not the staff, and not the guests who lose their favorite place.
What you can do instead
You don't have to ignore reviews, but consider them as part of a broader evaluation:
- Analyze complaints: Is it a structural problem or a one-time issue?
- Calculate the impact: What does a change cost in food expenses?
- Find smart solutions: Better presentation instead of more ingredients
- Monitor your numbers: Track food cost per dish
With proper food cost tracking you immediately see what changes in portions or ingredients do to your profitability, so you can make informed decisions.
How do you find the balance between reviews and profit?
Measure your current food cost per dish
Calculate for your 10 best-selling dishes what the ingredients cost. Divide this by your selling price excl. VAT and multiply by 100. Anything above 35% needs attention.
Analyze negative reviews for costs
Read complaints about portion sizes, quality or price. Calculate what it would cost to address these. Making a portion 20% larger increases your food cost by 20%.
Look for smart alternatives
Instead of more ingredients, look at better presentation, different garnish or more efficient purchasing. This way you improve the guest experience without sacrificing your profitability.
✨ Pro tip
Track your food cost for exactly 45 days after any portion size increase, not just customer feedback. A change that boosts your rating by 0.3 stars but raises food costs by 7% will slowly drain your bank account.

Frequently asked questions
Should I always take bad reviews about portion sizes seriously?
Not automatically. First check how many reviews mention this and calculate what larger portions would cost you. Sometimes it's smarter to better explain your pricing than to increase your portions.
How do I explain to guests why I don't give everything for free?
Focus on quality instead of quantity. Explain that you deliberately choose fresh, local ingredients. Guests usually appreciate honesty about your choices more than you'd think.
Can a high food cost sometimes be justified?
Yes, if you deliberately choose premium positioning. But then your selling price must also be premium. A food cost of 40% can work if you charge €50+ per dish, not at €20.
How often should I check my food cost?
At least monthly for your total food cost, and with every menu change per dish. Suppliers regularly raise prices, so what was 30% food cost last month might be 33% now.
What if my competitor gives large portions for the same price?
Check if they're actually making a profit. Many restaurants go bankrupt due to low margins. Focus on your own numbers and communicate your value: fresh ingredients, good preparation, nice atmosphere.
What's the biggest mistake restaurants make chasing 5-star reviews?
Saying yes to every customer complaint without calculating the cost. One negative review about small portions can lead to decisions that increase food costs by 6-8% permanently.
