Menu engineering: before and after, and which method fits your operating profile

For an independent with 10 to 25 tables and no standard recipe, cost portions before you classify

With 10 to 25 tables and no written recipe, forget the Kasavana-Smith matrix: your best option is four weeks of portion costing before you draw a single quadrant. The matrix eats contribution margin, and when that input comes in crooked the result is not imprecise, it is inverted, with a puzzle filed among the stars. July 2026, Bogotá: the best-selling dish on a menu carried 1,800 pesos of negative margin per unit, 62 went out weekly, and fourteen months of that add up to 111,600 pesos leaking every seven days. The owner kept it on page one out of pride. With the National Restaurant Association placing full-service median food cost at 32.0% of sales in its Restaurant Operations Report 2025, any menu that starts by classifying inherits the error in its input.

Better for operations with real food cost above 32%: work contribution dollars, not percentages

Contribution dollars, not percentages: that is the yardstick once your real food cost has crossed 32%, and the arithmetic settles it. A dish running 38% that leaves 22,000 pesos of margin feeds the register far better than one at 24% leaving 6,500, however spotless the second looks on a dashboard. The National Restaurant Association put 2024 median food cost at 32.0% in full service and 32.4% in limited service; locations under two million dollars in sales reported 33.7% against 31.0% for those above that line. Shaving one percentage point in a twenty-table restaurant almost never covers a month of payroll. Shifting the mix toward your six highest-contribution dishes does cover it, and it lands fast. I would rather defend a 38% dish that sells than a pretty 24% nobody orders.

When NOT to pick the popular option: three scenarios where the matrix lies?

The blog-standard matrix template collapses on its own in three scenarios. The first: inventory with no weekly count, since with waste unmeasured, theoretical and actual cost drift so far apart that classifying stops meaning anything.

The second shows up once the menu passes forty items in a two-station kitchen; there pass time rules rather than popularity, and a star that jams the line at peak destroys table turns. Third come prices frozen for over a year, while 40% of operators switched suppliers to answer rising costs, per TouchBistro 2024: that matrix photographs a restaurant that no longer exists. None of the three is rare in a Latin American independent, and a prettier menu fixes none of them. All three correct exercises begin in the storeroom, with a scale.

Four warning signs when comparing menu engineering methods

Four red flags disqualify a method before you hand it a week. One: it asks for the dish's food cost percentage and never once asks about portion yield or trim loss on the raw product. Two: it classifies on last month's sales, when seasonality in a Latin American independent swings the mix brutally from December to February. Three: it orders you to raise the price of the popular dish without touching the spec sheet, which works right up until the guest compares. And the fourth, the worst, hands over recommendations without demanding a standard recipe signed by the cook who executes it. A method that never walks into the kitchen is marketing dressed as cost control. The National Restaurant Association places optimal food cost between 28% and 35%, and no quadrant gets you near that range with no spec sheet behind it.

Better for kitchens with a defined concept: the food cost range moves your decision threshold

Mixing up food cost ranges across concepts is the diagnostic error we correct most often, because the threshold for a profitable dish depends on format and nothing else. The median food cost for limited-service restaurants sits at 32.4%, according to the National Restaurant Association (2025). A dish at 36% in a white-tablecloth grill is normal; the same 36% in a pizzeria is a hemorrhage, because high-margin pizza runs between 15% and 20% of menu price according to Sauce's 2025 menu engineering analysis. Run casual with a moderate average check and your useful cutoff sits in contribution dollars per hour of station time, never in a percentage copied from a guide written for somebody else's business. Design against the kitchen you have.

The bridge between a menu micro-decision and public policy: SATE Institute and Masterestaurant

Formal jobs are what that confusion between marketing and productivity policy costs, and I say it with figures in hand. Close to 5.6% of the region's urban labor force works in food-service MSMEs, according to the ILO Labour Overview for Latin America and the Caribbean 2025, with informality above 60% among firms under ten employees. The Twin Ecosystem Model splits the roles: SATE Institute sets the agenda and measures impact, while Masterestaurant S.A.S., the platform led by Diego F. Parra, supplies the operating instrument where the standard recipe lives and the cost per portion gets refreshed, mix reading on top. One menu decision then turns into aggregable data for credit scoring and for SDG indicators 8, 9 and 12. Multilateral banks funded a decade of reading that matrix, never the input that feeds it.

What would happen if you fixed the mix before the price: the twelve-month math?

Run the math the other way: pull the four dishes with negative contribution and lift your six highest-margin plates onto page one, instead of touching the price list.

In the Bogotá case, those 111,600 pesos recovered each week clear five million eight hundred thousand a year, with zero investment. The opposite road looks good for two months: you raise prices 8% without fixing the mix, average check improves, and by the third month frequency drops because the guest compares. One honest tension remains, since the flagship dish that bleeds money also pulls traffic; you resolve that with a redesigned spec sheet rather than a removal. Start this week: weigh the portions of your five best sellers, work out margin in pesos, and see which one finances the other four.

Four differences that decide the outcome

ORDER rules. The popular version starts by classifying dishes; the version that works starts by costing portions, because the menu engineering matrix is a function that consumes contribution margin, and a badly calculated input files a puzzle under stars and a dog under plowhorses. Invert that sequence and you do not get an imprecise answer, you get a backwards one, which is worse than skipping the exercise altogether. Next comes the UNIT OF ANALYSIS, and here nearly every piece of available material reasons in food cost percentage per dish. Percentage is a treacherous metric: a dish at 38% food cost carrying 22,000 pesos of margin feeds the till better than one at 24% carrying 6,500. Work in contribution pesos per unit sold and in total dish contribution for the period, the number that actually pays payroll.

Four differences that decide the outcome — in practice

Then the CHANNEL. Delivery platforms across Latin America charge a significant share of order value depending on the commercial agreement, so a dish with healthy dining-room margin can post negative contribution in the app. Cost by channel; otherwise your menu engineering ends up pushing, through the most expensive channel, precisely the dish least able to absorb that commission. FREQUENCY closes the list, and here I was wrong for years recommending annual reviews. With the food price volatility of recent cycles (FAO recorded double-digit year-on-year swings across several baskets between 2022 and 2025) a twelve-month-old costing is accounting fiction. Cost quarterly, read sales mix monthly; after the first build, incremental work drops to two or three hours.
