Restaurant founders who select their core menu items based only on taste-test feedback from acquaintances can easily overlook actual customer purchasing decisions and the operational burden on the kitchen. Before opening, menu tests should be conducted under fixed sales conditions, with records covering whether customers order the item, serving time, quality variation, menu costs, and the risk of ingredient waste. The results should be classified as retain, revise and retest, or remove, and then reflected in the final menu.
Taste Ratings and Purchasing Behavior Provide Different Information
Taste tests with acquaintances can help gather opinions about flavor intensity, texture, and portion size. However, responses given in a free or supportive evaluation setting are not the same as actual purchase decisions made after customers see the selling price, compare the item with other options, and pay for their order. In menu validation, the first question is not how many people said the food tasted good, but which customers ordered the item and under what circumstances.
Test-sale records should separately track each candidate menu item's number of customer exposures, number of orders, items ordered with it, repeat orders, and reasons for selection. Reasons for not ordering should also be reviewed by category, such as price, portion size, menu name, insufficient description, or difficulty understanding what is included. Rather than asking customers to complete lengthy surveys, it is more useful for decision-making to record questions and brief reactions from the ordering process under consistent categories.
Set Consistent Comparison Conditions Before Selling
For each candidate item, first define the target customer, intended dining occasion, selling price, portion size, core ingredients, cooking sequence, and standards for the finished dish. Fairly comparing selection rates becomes difficult if the same item is sold in different portions or at different prices depending on the date, or if only certain items receive excessive discounts or additional explanations. If an item was tested at a discount, it should be tested again at its regular price. Orders generated by discounts should not be interpreted as demand at the regular price.
The menu name and description are also part of the sales conditions. You must distinguish between customers who did not select an item because they could not understand it and those who understood it but rejected its price or composition. Refine the wording so first-time customers can quickly understand the item's characteristics and the reason for its price, but avoid changing several factors simultaneously during the test.
Measure the Time from Order to Service
Practical Theory of Restaurant Menu Development, a registered publication by author Kang Jong-heon (강종헌), presents a framework for evaluating test menu items based not only on customer responses but also on cooking time, workflow, peak-hour bottlenecks, and employee fatigue. From this perspective, even an item that receives a positive customer response can create significant operational risk if it depends on a particular worker or disrupts the speed and quality of other items when orders surge.
During test sales, record the time from order receipt to service, prep and finishing tasks, the number of portions that can be handled simultaneously, equipment occupancy, and worker movement. You should also check how much weight, appearance, flavor, and serving time vary when different workers follow the same recipe. A successful result achieved by only one experienced worker does not establish that the cooking process is reproducible.
- Process: Record advance preparation separately from work performed after an order is received.
- Workflow: Identify collision points as workers move between refrigerators, cooking stations, and washing areas.
- Simultaneous cooking: Determine which processes cause delays when orders for multiple items arrive together.
- Quality variation: Check whether standard weights and finished-dish specifications are maintained across different workers and times of day.
Include Losses Beyond Ingredient Costs
Menu costs cannot be assessed adequately by calculating only the ingredients used in a single serving. You should also compare how effectively ingredients are shared across menu items, minimum purchase quantities, weight loss during trimming and preparation, storage life, leftover inventory, and the risk of disposal after sales. If one candidate item requires additional dedicated ingredients and has highly variable sales, its actual burden may be greater than the food-cost percentage shown in the accounting records.
You should also examine the amount remaining after subtracting ingredient costs and other costs directly associated with each order from the selling price. Even if an item's food-cost percentage is low, it may contribute little toward covering fixed costs if it requires a long cooking time and sells infrequently. Conversely, an item that uses shared ingredients, can be produced consistently, and generates side-item orders may be evaluated separately for its cumulative contribution. However, do not insert arbitrary projected revenue. Calculations should be based on sales and usage confirmed during the test.
Do Not Remove an Item Solely Because Sales Are Low
First determine whether low sales are caused by the food itself or by how it is sold. Check whether the menu name or description was difficult to understand, whether the item lacked visibility on the menu, whether its price and portion size were appropriately balanced, and whether its role overlapped with a core menu item. Retesting under the same conditions after revising the wording or placement can help distinguish a menu problem from a communication problem.
- Retain: The item generates actual orders, while price acceptance, cooking consistency, costs, and waste remain within manageable operating limits.
- Revise and retest: The item has potential to be selected, but specific issues have been identified in its description, composition, price, or production process.
- Remove: Even after revisions, the item continues to face strong resistance from customers, or higher sales increase kitchen bottlenecks and waste.
A test sale is not temporary business activity conducted merely to produce a high sales result. It is a validation process for identifying core menu items that align customer choice, kitchen operations, and the profit structure. Treat the founder's preferences and feedback from acquaintances as reference opinions, and finalize the menu based on whether each item can be sold and produced repeatedly while generating a sustainable return. Before conducting an actual test, separately confirm the permits and reporting requirements that apply to the sales location and method with the relevant local authority.
