A practical guide to menu engineering for UK restaurants. Learn how to categorise dishes, analyse profitability, and redesign your menu to sell more of your highest-margin items.
Menu engineering is the systematic analysis of your menu items based on two factors: popularity (how often an item sells) and profitability (how much money you make on each sale). Developed by hospitality professors at Michigan State University in the 1980s, it's a data-driven approach that takes the guesswork out of menu design.
Instead of wondering why your restaurant isn't making enough profit despite being busy, menu engineering shows you exactly which dishes are carrying your business and which are dragging it down. It gives you a framework for making decisions about pricing, promotion, and even whether certain items belong on your menu at all.
For UK restaurants, takeaways, and delivery kitchens operating on thin margins — often 3-5% net profit after all costs — menu engineering isn't just helpful. It's essential. A well-engineered menu can increase your profitability by 10-15% without adding a single new customer or raising prices across the board.
Menu engineering divides every item on your menu into one of four categories based on popularity and profitability. Think of it as a matrix with two axes: high/low popularity and high/low profitability.
Stars are your menu heroes. These dishes sell well and make you good money on each sale. They're the items that built your reputation and keep customers coming back. For most restaurants, stars represent 20-30% of the menu but generate 50-60% of total profit.
What to do with Stars:
Plow Horses are popular dishes that don't make much money. Customers love them and order them frequently, but your margins are thin. Classic examples include fish and chips at a seaside takeaway, or a basic margherita pizza at an Italian restaurant. These items often become Plow Horses because you priced them competitively to attract customers, or because ingredient costs have crept up over time.
What to do with Plow Horses:
Puzzles are dishes that make excellent margins but don't sell well. They're the hidden gems of your menu — if only customers would order them. Puzzles often happen when a dish is delicious and profitable but hidden in an obscure corner of the menu, or described poorly, or simply unknown to your customers.
What to do with Puzzles:
Dogs are dishes that neither sell well nor make money. They're the dead weight on your menu — taking up space, confusing customers, and complicating your kitchen operations. Every Dog on your menu is a distraction from your Stars and a missed opportunity to sell something more profitable.
What to do with Dogs:
To categorise your menu items, you need data on both popularity and profitability. Here's how to calculate each.
Popularity is straightforward: what percentage of total orders does each item represent? Most POS systems can run this report for you. If you're tracking manually, count orders over a representative period (ideally 2-4 weeks) and divide by total orders.
| Item | Orders | Total Orders | Popularity % |
|---|---|---|---|
| Chicken Tikka Masala | 340 | 2,000 | 17% |
| Lamb Rogan Josh | 180 | 2,000 | 9% |
| Vegetable Korma | 120 | 2,000 | 6% |
Profitability requires calculating the contribution margin for each dish — the selling price minus the direct costs (food and packaging).
Step 1: Calculate food cost per portion
List every ingredient in the dish and its cost. Be precise: weigh portions, check invoices, and include everything down to the oil and garnishes.
| Ingredient | Portion | Cost |
|---|---|---|
| Chicken breast | 200g | £1.20 |
| Sauce ingredients | 150g | £0.45 |
| Rice | 200g | £0.20 |
| Naan bread | 1 | £0.35 |
| Garnish, oil, spices | — | £0.15 |
| Total food cost | — | £2.35 |
Step 2: Add packaging costs (for delivery/takeaway)
Include containers, bags, napkins, and cutlery. For dine-in, this may be minimal or zero.
Step 3: Calculate contribution margin
Selling price minus (food cost + packaging cost) = contribution margin
Example: £11.99 - (£2.35 + £0.45) = £9.19 contribution margin
Step 4: Calculate food cost percentage
(Food cost ÷ Selling price) × 100 = food cost percentage
Example: (£2.35 ÷ £11.99) × 100 = 19.6% food cost
To categorise items, you need to define "high" and "low" profitability. Most UK restaurants aim for a food cost percentage of 25-30%. Use this as your benchmark:
Items in the 25-30% range are borderline — track them closely and look for opportunities to improve margins.
Once you have popularity and profitability data for every item, plot them on a matrix:
| High Profitability | Low Profitability | |
|---|---|---|
| High Popularity | ⭐ Stars — Promote heavily | 🐴 Plow Horses — Improve margins |
| Low Popularity | 🧩 Puzzles — Increase visibility | 🐕 Dogs — Remove or reinvent |
A typical restaurant analysis might look like this:
The goal: turn Plow Horses into Stars, turn Puzzles into Stars, and eliminate Dogs to make room for new potential Stars.
Menu engineering analysis is worthless if you don't act on it. Here's how to redesign your menu to sell more Stars and Puzzles.
Apply the Golden Triangle — centre, top-right, and top-left — to your Stars and most promising Puzzles. This is where eyes go first. Don't waste prime real estate on Dogs or even Plow Horses unless they're essential for competitive reasons.
For more on visual placement and menu psychology, see our guide on menu psychology and photo placement.
Stars should always have photos — they're your signature dishes. Puzzles desperately need photos to increase their visibility. Use boxes, borders, or colour highlights sparingly, and only for Stars or high-potential Puzzles you're promoting.
Remember: a professional photo can increase orders by up to 30%. If you've identified a Puzzle that could become a Star with more visibility, SnackSnap can create the professional menu photo you need in under 60 seconds from your phone shot.
Rewrite descriptions for Puzzles to emphasise what makes them special. Use sensory language: "tender," "crispy," "slow-cooked," "house-made." Mention provenance where relevant: "locally sourced," "award-winning."
For Stars, keep descriptions consistent — customers return for what they know and love.
For Plow Horses, consider small price increases. A 50p increase on a £10 dish is only 5% — unlikely to trigger sticker shock, but it can turn a Plow Horse into a Star if the margin improves enough.
For Stars with strong customer loyalty, you may have room to increase prices more aggressively. Test gradually and monitor order volume.
Be ruthless. Every Dog you remove simplifies kitchen operations, reduces waste, and frees up menu space for potential new Stars. Before adding any new dish, ask: "Is this more likely to be a Star than the worst item currently on our menu?"
Delivery platforms like Deliveroo, Just Eat, and Uber Eats present unique challenges and opportunities for menu engineering.
Delivery platforms give you detailed analytics: impressions, clicks, conversion rates, and customer behaviour patterns. Use this data to refine your engineering analysis. An item with high impressions but low conversion might be a Puzzle that needs a better photo or description.
On delivery platforms, photos aren't optional — they're essential. Customers skip items without images. Every Star should have a professional photo. Every Puzzle needs one to have any chance of becoming a Star.
Platform photos have specific requirements: bright backgrounds, tight crops, and consistent styling. SnackSnap offers one-click exports sized perfectly for each platform, so your engineering analysis can be matched with visuals that convert.
Organise your platform menu strategically:

Bundles are powerful on delivery platforms. They increase average order value and let you package Stars with Puzzles or high-margin sides. "Any main + rice + naan for £14.99" feels like a deal to customers while improving your margins compared to à la carte ordering.
Menu engineering without data is just guessing. You need actual sales figures and costed recipes. Invest the time to track this properly — the insights will transform your profitability.
Food costs change. Customer preferences shift. A Star can become a Plow Horse if ingredient prices spike. Re-run your menu engineering analysis quarterly, and always after significant cost changes or menu updates.
Contribution margin matters more than food cost percentage. A dish with 40% food cost but a £12 contribution margin may be more valuable than a dish with 20% food cost and a £4 contribution margin. Always look at the actual pounds and pence.
Some Plow Horses serve a strategic purpose. They may bring in price-sensitive customers who then order high-margin drinks and sides. They may be essential for competitive positioning. Don't remove them blindly — understand their role in your overall strategy.
You can engineer the perfect menu on paper, but if your Puzzles don't have professional photos, they'll stay Puzzles. Visual appeal is the bridge between engineering analysis and customer behaviour. See examples of how professional photography transforms menu performance.
Make menu engineering a regular practice, not a one-off project. Here's a sustainable routine:
Initial setup — gathering data and categorising your current menu — takes 4-6 hours for a typical restaurant with 30-40 items. Once the system is in place, quarterly updates take 1-2 hours. The time investment pays for itself many times over through improved profitability.
No. A spreadsheet is sufficient for most independent restaurants. Track item names, selling price, food cost, contribution margin, and order count. Calculate popularity percentage and use the matrix to categorise. As you grow, specialised restaurant management software can automate this.
Yes. Delivery packaging costs affect profitability calculations. Popular items may differ between channels. And photo strategy is different — delivery platforms require photos on every item, while printed menus use them more sparingly. Run separate analyses if your menus differ significantly.
Absolutely. Small menus often see the biggest impact because each item represents a larger share of revenue. With only 15-20 items, every Star, Plow Horse, Puzzle, and Dog has an outsized impact on your bottom line. Menu engineering is arguably more important for small operations.
High food cost doesn't automatically mean low profitability. Look at contribution margin, not just percentages. A £20 dish with £8 food cost (40%) contributes £12 — more than a £10 dish with £3 food cost (30%) contributing £7. If the £20 dish sells well, it's a Star. Monitor food costs closely, but don't confuse percentage with pounds.
Start with visibility: move it to prime menu real estate and add a professional photo. Rewrite the description to make it sound irresistible. Train staff to recommend it. Consider a limited-time promotion to get customers to try it. If it still doesn't sell after these changes, it may be a fundamental mismatch with your customer base — replace it with something new.
Menu engineering transforms menu design from art into science. Instead of guessing what customers want or clinging to dishes for sentimental reasons, you make decisions based on data: what sells, what profits, and what deserves your attention.
The framework is simple but powerful:
Run this analysis quarterly. Make incremental improvements. Track the results. Over time, your menu becomes a finely-tuned profit engine — one where every item earns its place and contributes to your success.
For UK restaurants navigating tight margins and fierce competition, menu engineering isn't optional. It's how you survive and thrive.
Menu engineering analysis often reveals that your most profitable dishes are hiding in plain sight — great margins, terrible sales. The fix is usually visibility: better placement, compelling descriptions, and professional photos that make customers want to order.
