Most restaurants focus on either menu optimization or staff training - but never both simultaneously. The real profit explosion happens when you combine strategic dish promotion with targeted upselling techniques. Calculate this correctly, and you'll see margins jump 15-25% within weeks.
The basics: menu engineering matrix
Menu engineering divides your dishes into 4 categories based on popularity and profitability:
- Stars: Popular and profitable (promote!)
- Plowhorses: Popular but low profit margin (adjust price or optimize ingredients)
- Puzzles: High profit margin but not popular (promote more or remove from menu)
- Dogs: Low popularity and low profit margin (eliminate)
💡 Menu engineering example:
Restaurant with 5 main courses, 200 covers/week:
- Steak: 60 sold, margin €12 = Star
- Pasta: 80 sold, margin €6 = Plowhorse
- Fish: 20 sold, margin €14 = Puzzle
- Burger: 30 sold, margin €8 = Normal
- Salad: 10 sold, margin €4 = Dog
Focus on: selling more steak and fish, less pasta and salad
Calculating upselling: increasing average check
Upselling works magic with your Stars and Puzzles. Train your team to recommend these add-ons:
- Side dishes with high margin (fries, vegetables, sauces)
- Beverages (especially wine - margin 60-70%)
- Desserts (often margin 70%+)
- Upgrades (extra meat, premium ingredients)
💡 Upselling impact example:
200 covers/week, average check €28:
- 20% of guests order a side dish (€4.50, margin €3)
- 40% of guests order dessert (€7.50, margin €5)
- 60% of guests order an extra drink (€4, margin €2.80)
Extra margin per week: (40×€3) + (80×€5) + (120×€2.80) = €856
Calculating the combination
Menu engineering ensures your profitable dishes get sold more often. Upselling boosts margin per guest. Together? They multiply each other's impact.
But here's where most owners mess up - they don't track the interaction properly. I've seen this mistake cost restaurants EUR 300-350 per month in lost profits because they calculate each strategy separately instead of measuring the combined effect.
⚠️ Note:
Train your team specifically on your Stars and Puzzles. There's no point upselling Dogs - you're not selling enough of them anyway.
Practical formulas
Calculate the impact in 3 steps:
Step 1: Menu engineering impact
Difference in average margin per dish × number of additional sales of profitable dishes
Step 2: Upselling impact
Number of guests × upselling success rate × average margin per upsell
Step 3: Total impact
Menu engineering impact + Upselling impact = Extra margin per period
💡 Complete example:
Restaurant with 1000 covers/month:
- Menu engineering: 200 guests choose Star instead of Plowhorse = 200 × €6 extra margin = €1,200
- Upselling: 300 guests order side dish/dessert = 300 × €4 margin = €1,200
- Total: €2,400 extra per month
- Per year: €28,800 extra margin
ROI training: €28,800 vs. €2,000 training costs = 1340% ROI
Implementation in practice
Start small and measure everything. Use your POS system to track which dishes and add-ons get sold. Many restaurants use tools like KitchenNmbrs to track profitability per dish and see which menu engineering adjustments yield the most results.
First focus on training your team to upsell your Stars. Once that works smoothly, adjust your menu to sell more Stars and eliminate Dogs.
How do you calculate margin impact? (step by step)
Analyze your current menu performance
Divide your dishes into the 4 categories: Stars, Plowhorses, Puzzles, and Dogs. Calculate the margin per dish and count how many you sell per week. Focus on your top 5-8 dishes.
Calculate menu engineering impact
Assume that 20% of your Plowhorse sales shift to Stars. Multiply this number by the margin difference between the two dishes. This gives you the extra margin from menu engineering.
Calculate upselling impact
Set a realistic success rate (start with 15-25%). Multiply your number of guests × success rate × average margin per upsell. Add this to your menu engineering impact for the total extra margin.
✨ Pro tip
Track your top 3 Stars for exactly 6 weeks: measure both their individual sales increase AND how often they get upsold with sides or desserts. This dual metric reveals your true profit multiplication factor.

Frequently asked questions
What success rate can I expect with upselling?
A well-trained team achieves 20-30% success rate on side dishes and 15-25% on desserts. Start realistically with 15% and build up gradually.
Should I promote all dishes equally hard?
No, focus on your Stars (popular and profitable) and Puzzles (profitable but not popular). Dogs and Plowhorses don't deliver enough to invest much energy in.
How long before I see results?
Menu engineering works immediately once you adjust the menu. Upselling training typically takes 2-4 weeks before your team masters it and results become visible.
Can I combine this with seasonal pricing?
Absolutely - seasonal ingredient prices make menu engineering even more important. Your Stars can shift per season based on purchasing costs and guest preferences.
What if my team finds it pushy?
Train them to make suggestions, not push. 'Would you like fries with that?' works better than 'You really must try our dessert.' Focus on hospitality, not sales.
How do I handle guests who always order the same dish?
Use your regulars as upselling opportunities for sides and drinks instead of trying to change their main course. They're already comfortable - build on that trust.
