The Hidden Economics of Restaurant Menus

Running a profitable restaurant right now isn’t easy. Costs are up, customers are more price-sensitive, and there’s only so far you can push prices before people start to notice. Menu optimisation remains one of the most powerful levers to protect margins. Yet, in reality, many approach it on autopilot, making small, reactive tweaks a few times a year, nudging prices up here and there without stepping back to properly interrogate performance. The challenge is often a lack of time and resource. Proper menu engineering requires accurate data, analysis, testing, and cross-team alignment, all of which are difficult to prioritise when day-to-day operations demand attention. As a result, significant opportunities can be left on the table.

Menu optimisation is a complicated balancing act of commercial considerations, competitive environment, operations and guest perceptions. Every dish carries a different contribution margin, and without clear visibility at item level, it is impossible to truly understand what is driving profits. A robust product mix analysis changes this but relies on accurate input data from BOH teams. By examining volume, revenue, and margin contribution per dish, operators can identify which items are pulling their weight, which are underperforming, and where there is opportunity to improve. Importantly, margin should not be viewed in isolation. Some dishes may appear highly attractive from a GP perspective but require disproportionate labour, preparation time or specialist skills, making their true economic contribution less compelling once operational complexity is taken into account.

This level of insight enables more precise, targeted decision-making, rather than blanket price increases which can damage value perception. Ultimately, the goal is not simply to increase margins, but to improve profitability while maintaining the quality, value and experience that keep guests coming back. We like to apply an adapted BCG-style matrix to PMix analysis, plotting items on axes of revenue and GP margin to split items out across four quadrants:

·       Core: high volume, high GP

·       Margin diluters: high volume, low GP

·       Watchlist: low volume, high GP

·       Deadweight: low volume, low GP

The margin diluters form an instant brief for procurement teams or partners. This is where the biggest impact of any improvements is likely to be felt. The ideal outcome is to secure the same quality ingredients at lower cost while holding menu prices. Failing that, these items are prime candidates for price increases - where supported by competitor benchmarking and management judgement - or portion adjustments (“shrinkflation”), provided changes are subtle enough not to be perceptible to guests.

The highest spend ingredients in the core items are also good candidates for procurement focus, simply because of their volume. Teams are often very loyal to suppliers, and rightly so, but it can mean opportunities are missed. We brought in a procurement specialist to a client recently and they were able to negotiate significant discounts with existing suppliers just by running an audit process, while finding cheaper alternatives for less emotive categories like cleaning products. They had never considered a procurement partner, but it’s now helping them hold prices. Watchlist items tend to sit in the middle, neither driving profit nor causing harm. As a result, each one should earn its place, whether by bulking out a category, acting as a pricing decoy, supporting ingredient cross-utilisation, or catering to dietary requirements. Deadweight items would ideally be removed unless they perform one of the important functions listed above in which case their prices should be reviewed.

The playbook for margin protection tends to follow a familiar set of moves: procurement and supplier negotiation, selective price increases, portion or ingredient adjustments (often paired with presentation tweaks), culling underperforming items, and introducing new dishes to shift sales towards higher-margin options.

With all of the above, it’s essential to look at items through two lenses: percentage margin and cash margin. Wine is the classic example. If your house wine sells at £40 with a 4x mark-up, it delivers £30 gross profit and a 75% GP margin. A more premium bottle at £80 with a 3x mark-up delivers roughly £53 gross profit and a ~67% GP margin. So, while the percentage margin drops, the cash profit increases. In simple terms, you’re better off when guests trade up, and well-designed menus subtly encourage that behaviour. The same logic applies across the menu. Higher-ticket items like steak or fish can carry lower percentage margins but still generate stronger cash contribution. And ultimately, it’s that cash contribution that does most of the heavy lifting when it comes to overall profitability. Percentage margin doesn’t pay the bills, cash does!

Another important angle is menu architecture. How dishes are structured, grouped, and presented directly influences customer choice. There are a number of approaches, from stretch architecture to “good, better, best” tiering or single price-point menus. Which one is right depends heavily on the concept and customer base, but all are designed to shape spend. For example, one client found that adding a couple of premium grilled meat dishes increased sales of other higher-priced items, despite the new dishes themselves selling relatively little – a classic example of decoy pricing in action. Then there is the menu layout itself - placement of hero dishes, alongside techniques like decoy pricing, can guide behaviour to benefit guests and businesses. Then of course overall menu length – refinement reduces operational complexity often enabling teams to deliver greater consistency and not overwhelming customers with choice.

True optimisation combines these changes with structured product development. New dishes help shift focus away from price increases while adding freshness and talkability, but they need to be guided by clear parameters from the outset: what role they should play (seasonal refresh, health trends, driving frequency), what margin thresholds they must meet, and what level of operational complexity is acceptable. A formal NPD framework ensures this discipline, paired with a regular review cycle - typically every six months - to reassess performance and decide what stays, rotates, or goes. Critically, it also means being clear on what not to do. Often we see 20% of the menu driving 80% of sales. Without discipline, new dishes simply dilute that core rather than strengthen it.

Done well, menu optimisation is win-win, improving the guest proposition while simplifying operations and protecting margins. In a tougher market, the operators who come out on top are those who look most honestly at what is working, have the discipline to cut what isn’t, and understand the value of the old adage “less is more”.
