Running a restaurant menu is like tending a garden - some plants thrive while others drain resources without producing fruit. Underperforming dishes steal menu space, force you to buy ingredients that spoil, and block opportunities to showcase your profitable stars. This analysis reveals exactly which dishes are choking your menu's potential.
The four quadrants of your menu
Every dish lands in one of four distinct categories. Cross-referencing popularity against profitability instantly reveals which items demand immediate action.
💡 The four types:
- Stars: Popular + profitable (keep them!)
- Plowhorses: Popular + not profitable (raise prices)
- Puzzles: Not popular + profitable (promote more)
- Dogs: Not popular + not profitable (remove them!)
Gather your sales and cost data
You'll need two key metrics per dish: sales volume and profit margins. Pull your POS data from the previous 3 months - anything shorter gives you incomplete insights.
⚠️ Note:
Three months minimum prevents single bad weeks from distorting results. Seasonal items need separate analysis within their active periods.
Calculate popularity per dish
Popularity equals each dish's percentage of total sales volume. Sum up every portion sold across all menu items, then divide individual dish sales by this total.
💡 Example calculation:
Last 3 months:
- Carbonara: 450 portions
- Steak: 320 portions
- Salmon: 180 portions
- Total all dishes: 2,400 portions
Carbonara popularity: 450 ÷ 2,400 = 18.8%
Calculate profitability per dish
Profitability means gross profit per portion. Subtract ingredient costs from your selling price (excluding VAT). Higher gross profit signals better profitability.
💡 Example profit calculation:
- Carbonara: €18.50 ÷ 1.09 = €16.97 excl. VAT
- Ingredient costs: €5.10
- Gross profit: €16.97 - €5.10 = €11.87
Compare this €11.87 against other dishes.
Draw your menu matrix
Plot popularity on the X-axis, profitability on the Y-axis. Use each metric's average as your dividing lines. Items landing in the bottom-left quadrant are your 'dogs' - they're eating your profits.
- Top right (Stars): Push these harder through promotion
- Bottom right (Plowhorses): Increase prices or cut ingredient costs
- Top left (Puzzles): Improve marketing or menu descriptions
- Bottom left (Dogs): Cut them from the menu
Signs that a dish needs to go
Beyond poor popularity and profitability numbers, watch for these red flags that signal menu clutter:
- Ingredients purchased solely for this dish (frequent spoilage)
- Complicated prep work that bottlenecks kitchen flow
- Recurring customer complaints about taste or presentation
- Seasonal items overstaying their welcome year-round
⚠️ Note:
Don't axe more than 2-3 dishes simultaneously. Customers need adjustment time for menu changes.
The cost of bad dishes
After managing kitchen operations for nearly a decade, I've seen how poorly performing dishes drain resources beyond their obvious losses. You're buying ingredients that rot, confusing customers with too many options, and sacrificing valuable menu real estate that profitable alternatives could occupy.
💡 Cost example:
Dish sells 2x per week, ingredient costs €8 per portion:
- Sales: 2 × 52 = 104 portions/year
- Waste from spoilage: 20 portions/year (€160)
- Missed opportunity for better dish: €5 extra profit × 104 = €520
Total missed profit: €680 per year
Replace underperforming dishes
Don't just remove - replace strategically. Study your successful dishes' flavor profiles and price points, then introduce similar winners.
Test replacements as daily specials first. This prevents you from swapping one 'dog' for another and gives you real performance data before committing menu space.
How do you analyze your menu systematically?
Gather sales and cost data per dish
Get till data from 3 months. Count per dish: number of portions sold, selling price, ingredient costs. These are your basic data for the analysis.
Calculate popularity and profitability
Popularity = portions of dish ÷ total portions × 100%. Profitability = selling price excl. VAT - ingredient costs. Rank all dishes on both criteria.
Identify your 'dogs' and make an action plan
Dishes below average popularity AND profitability are candidates for removal. Start with the worst performers and replace a maximum of 2-3 dishes at a time.
✨ Pro tip
Track dishes that require unique ingredients used nowhere else on your menu - if they're selling fewer than 15 portions weekly, you're likely losing money on spoilage and inventory carrying costs.

Frequently asked questions
How often should I analyze my menu?
Run this complete analysis every 6 months. Monthly spot-checks of your top 5 performers and bottom 5 laggards help catch trends early.
What if a dish has sentimental value?
Business-wise, every dish must justify its menu position. If you absolutely can't part with it, raise the price or slash ingredient costs to force profitability.
Can I save bad dishes with better marketing?
Only if poor popularity is the sole issue, not profitability problems. Fix your numbers first through pricing or cost adjustments, then market it.
Should I judge seasonal dishes differently?
Absolutely - analyze seasonal items only within their active periods. A summer dessert that flops in winter might dominate during peak season.
