Is your kitchen still earning its keep? A weekly review that works
TL;DR: How long a restaurant has been open tells you nothing about whether it is making money now. Every kitchen needs a regular, honest check on its menu, costs, labour and buying. Thirty minutes a week, using real prep sheets, invoices and service notes, will tell you more than any quarterly meeting.
So how do you know whether your kitchen is still earning its keep? You check the operation in front of you, not the story of how well it used to do. A busy pass is not proof of profit. A kitchen can be well loved by regulars and full of hard-working people and still fail today’s commercial test. The trouble is that chefs often spot it late, because there is always prep to finish, an order to place and a gap on the rota. The numbers need a fixed place in the week, not a promise to look at them when things calm down.
Put the menu through a service test
Do not start with the menu price. Start with what each dish demands during a live service.
Ask the chef in each section to talk you through the plates that sell steadily. How many components need preparing? Which ingredients are bought for that dish alone? What happens when the garnish runs out at half eight? Does the plate hold on the pass, or does it cause refires?
Then put those answers beside the spec sheet. A dish can look fine on a costed recipe while quietly eating labour, fridge space and waste. At your next menu review, work through it in this order:
- List the dishes that sell consistently and the ones that create disproportionate work.
- Check portion, yield and trim on the ingredients driving your purchase order.
- Watch one full service and note where handovers, delays and waste occur.
- Decide whether each problem dish should be simplified, repriced, moved or removed.
This is not about stripping the menu until it is dull. A good signature dish earns its complexity. A weak seller with a long prep list does not.
Cost the kitchen as it is actually run
A recipe cost is a starting point, not a verdict. It only holds if the portion on the plate matches the costing, the product arrives to the spec you assumed and the trim is recorded rather than guessed.
Take one product that appears in several sections and follow it from delivery to bin. Check the invoice price against the agreed spec, the weight received, the trim and the usable yield. Then watch how it is portioned and labelled in the walk-in. A disciplined check on a few high-use ingredients will tell you whether your theoretical margin is surviving contact with the kitchen.
Bring the section chef into it. Not to turn them into an accountant, but to give them control of what they can influence: portioning, rotation, trimming and waste. Once a cook understands that an over-portioned protein means fewer profitable covers, they will act long before month-end exposes it.
Match the brigade to the pattern of trade.
The labour question is not simply whether the rota is expensive. It is whether the right people are on the right jobs at the right time. A quiet afternoon can still cost you if it leaves the night team finishing mise en place under pressure. Equally, people standing in a section with little to do can hide a menu or booking problem.
On Monday morning, take last week’s rota, bookings and service notes, mark the pinch points and ask three questions:
- Which jobs must be done before the first ticket prints?
- Which jobs are being done twice because the handover is unclear?
- Which section becomes the bottleneck when covers rise?
The answers should change the rota, the prep list or the menu. If they change nothing, the exercise was only paperwork.
Make buying support the menu.
Supplier relationships matter most when you use them to protect a clear specification. The head chef, whoever orders and the supplier should all be working to the same requirement: grade, pack size, usable yield, delivery day and acceptable substitute.
A substitute agreed before service can be perfectly sensible. One that turns up unannounced and forces a change in portion, garnish or menu description is expensive. Keep an approved-substitute list for your riskiest products, and put it where the person receiving deliveries can actually use it.
Treat short deliveries the same way you treat waste. Do not just send someone to the cash and carry and forget about it. Record what changed, what it cost in time and whether the menu needs a better fallback.
Turn it into a weekly routine.
Give the review a regular slot. Thirty focused minutes after the weekly stock check beats a long quarterly meeting full of old figures. Bring the head chef, the person who places orders and whoever understands the bookings, and work from real prep sheets, invoices and service notes.
Leave with three actions: one for the menu, one for buying and one for labour, each with a name and a date. Next week, check whether each one changed what happens on the pass or in the walk-in. That is how the numbers become kitchen practice rather than a report nobody reads.

Frequently Asked Questions
How often should I review the menu commercially?
Look at the high-use, high-waste and labour-heavy parts every week through service notes, prep and purchasing. A full menu review can follow your normal trading cycle, but waiting for a relaunch means missing problems you could fix now.
What should I check first if food cost has moved?
A product bought often and used across several dishes. Compare the invoice, delivered weight, usable yield and actual portion. Our 60 Minute Food Cost Audit walks you through it.
Does simplifying a dish mean lowering standards?
No. Simplifying should remove work that does nothing for the guest’s plate or the reliability of service. Keep complexity where it delivers a clear result, and challenge it where it only creates waste, delay or inconsistency.
Who should be in the weekly review?
The person running the kitchen, the person placing orders and someone who understands bookings. The point is to connect what was bought and prepped with what actually happened in service.
