Three-quarters of diners now want smaller portions, and venues that price them fairly are unlocking waste savings, new occasions and a quality signal all at once.
For decades, generosity in Australian hospitality has been measured in grams. A bigger plate meant better value, and value meant volume. That equation has broken. Diners are eating differently, spending differently and, increasingly, asking for less food, not because they want less from you, but because they want the right amount of portion sizing for how they actually eat.
The demand shift is now overwhelming
According to the National Restaurant Association’s annual survey, 74 per cent of customers want smaller portions, and 64 per cent of consumers are replacing traditional meals with snacks throughout the day. A Lightspeed Commerce survey covered by Morning Brew found that 44 per cent of adults order from the kids’ menu to save money and eat less, and Circana’s foodservice trends research shows 35 per cent of restaurant consumers are ordering smaller portions than normal.
When 44 per cent of adults are ordering off a menu designed for children, that is not a diet trend. That is a product gap.
The waste and margin case
Right-sizing is one of the rare moves that improves the guest offer and the P&L simultaneously. The Datassential × ReFED Restaurant Portion Size Study 2025 estimates that offering different portion sizes could cut 2.35 million tons of food waste a year and save the foodservice sector US$547 million, with 59 per cent of consumers, and 73 per cent of GLP-1 users, more likely to visit a restaurant that offers flexible portion options.
The Australian waste economics make the argument locally. Australia wastes 7.6 million tonnes of food a year, costing $36.6 billion, with hospitality responsible for 16 per cent of that, roughly 1.2 million tonnes, according to End Food Waste Australia’s Foodservice Sector Action Plan and Restaurant & Catering Australia. Foodservice waste alone is worth $6.4 billion, roughly $66,740 per foodservice business per year, and only 23 per cent of foodservice businesses regularly audit their food waste.
End Food Waste Australia’s segment benchmarks, drawn from UK WRAP research, are a useful sizing tool: casual dining wastes 380 g per cover (50 per cent prep waste, 29 per cent plate waste); fine dining 310 g; basic dining 170 g, where plate waste is highest of the four segments at 46 per cent. Plate waste at that level means guests are telling you your portion sizing is wrong, one scraping at a time.
The pricing constraint you cannot ignore
Right-sizing fails when it reads as shrinkflation. The same Datassential × ReFED research found that 75 per cent of consumers say a smaller portion at almost the same price feels like a rip-off, but 49 per cent will pay a little more for a portion that fits their appetite. The distinction matters enormously. Guests will not accept less food at the same price. They will pay a premium for the correct amount of food, clearly framed as a choice they made.
What good execution looks like
Olive Garden trialled a reduced-portion, lower-price section covering seven dinner entrées at nearly half its restaurants; its internal affordability index rose 15 per cent, and management credited the menu with bringing diners back into the regular rotation. P.F. Chang’s now offers “traditional” and “medium” sizes across all entrées, and The Cheesecake Factory launched a sub-$10 “Bites” section, as CNN reported on the industry-wide shift.
For Australian operators, we suggest a staged approach to portion sizing:
-
Audit plate waste by dish before changing anything, the data will nominate your candidates.
-
Offer two sizes on high-value proteins, not on everything.
-
Name the sizes honestly (“regular” and “generous” outperforms “small”).
-
Reprice by food cost plus a fair margin, not by a flat percentage discount.
-
Train the floor to sell the smaller size as a choice, never as a concession.
Portion architecture sits right at the intersection of menu engineering, food-cost control and guest experience, which is exactly where our work tends to live. If you would like to model what disciplined portion sizing would do to your food cost and your average spend, the Alto Cibum team can build that case with you.
