SEARCH QUESTION
Why are restaurant sales falling, and what should be checked first?
A diagnostic guide that separates traffic, conversion, average check, repeat visits, menu, cost, service, and channel issues before spending more on advertising.
CORE ANSWER
Restaurant Sales Slump Diagnosis · Core answer
A sales decline is not one problem. Break sales into customer count and average check, then compare by channel, daypart, weekday, menu, and customer type. Fix operational leakage before increasing advertising, because more traffic does not solve low conversion, weak repeat visits, or poor unit economics.
NUMBERS TO CHECK01 02 03 04
Numbers you should actually check
Average check and menu mix
Average order value, discount level, premium-item share, add-on sales, and low-margin menu share
Conversion and repeat rate
Search views, calls, reservations, visits, orders, reviews, and repeat purchases
Contribution margin
Sales remaining after food, packaging, payment, platform, and promotion costs
CHECKLIST
Items to verify before deciding
- Is the decline caused by fewer customers, lower average check, or both?
- Which channel, weekday, daypart, and menu changed first?
- Are menu availability, waiting time, service, cleanliness, and review issues reducing conversion?
- Do promotions generate contribution margin after discounts and platform costs?
- Are repeat customers declining even though new-customer traffic is stable?
- Have you selected one or two measurable actions instead of changing everything at once?
FIELD CASE
A common field situation
A hypothetical store increased advertising after sales fell, but most new visitors did not reorder because the main menu was often sold out and delivery time was unstable. The immediate issue was operating reliability, not awareness.
