In short: A restaurant’s advertising budget usually ends up on Saturday, the day that needs it least. Across 40 restaurants we manage, over thirteen weeks of summer 2026, Saturday took 16.5% of spend and 17.4% of actions (directions, calls, bookings); Monday, 12% of each. A weekday action costs about 9% more (€0.56 Monday to Thursday against €0.51 Friday to Sunday) because fewer people are searching, but it is the only one that fills a table that would not have filled itself. It is not about spending more; it is about moving the budget: eight weeks of bookings, shift by shift, two chosen gaps, ads scheduled by day and hour, and a weekly review. In one of the restaurants we manage, moving the budget to Monday and Tuesday brought 31% more weekday bookings in a quarter, with the same investment.
On a Saturday night your restaurant fills up on its own. You could switch off the sign, hide the menu and answer the phone in Aramaic, and it would fill up just the same. And yet that's where the money for restaurant advertising almost always ends up: on the day that needs it least, because that's where the figures look best and it's a pleasure to look at them. Meanwhile, you spend Tuesday counting empty chairs. The right question isn't how much to spend: it's which days are short of people and what it costs to bring them in.
Budget isn't the problem
What's missing is hardly ever money. What's missing is people on weekdays, especially Mondays and Tuesdays (poor things). And that's where an ad really can change something, because you're not competing with Saturday's momentum: you're competing with someone who hasn't decided where to have dinner yet and who, with a bit of luck, is looking at their phone and feeling hungry.
Moving the budget doesn't mean spending more. It means asking, before touching a single campaign, which days and which services really need people. And the answer isn't in any tool with colourful charts: it's in the bookings diary, which has been telling you for years without anyone paying it the slightest attention.
Advertising doesn't fix an empty restaurant. It fixes one specific empty day.
What the numbers say
Since opinions are free, we went and looked. These are the Google campaigns of 40 restaurants we manage, over thirteen weeks of summer 2026. We call it an 'action' when someone asks for directions, taps to call or taps to book after seeing the ad.
Sample: Google Ads campaigns of 40 restaurants managed by BL Gastro, thirteen weeks of summer 2026 (June–August). ‘Action’ = asking for directions, calling or tapping book after seeing the ad. These are our own figures, not an industry average.
- Saturday takes the lion's share: 16.5% of the spend and 17.4% of the actions. Monday, the ugly duckling of the week, 12% of each.
- A weekday action costs more, not less: around €0.56 from Monday to Thursday against €0.51 from Friday to Sunday. It happens in almost nine out of ten accounts, so it's no coincidence.
- The difference, mind you, is small: 9% in the median account.
And here's the catch. If you let Google share it out as it pleases, it goes wherever each action comes cheapest, which is the weekend: there are more people searching and they take less convincing. For the machine, a resounding success. For you, paying for a Saturday table that would have filled anyway. The Tuesday action costs 9% more and it's the only one you actually need.
Two caveats, because we're serious people here: these are our own accounts and a single summer, not an X-ray of the sector. And someone asking for directions isn't sitting down yet, let alone ordering a vermouth.
How to move the budget to the quiet days
1. Look at the bookings diary, not the ads dashboard
Eight weeks back, service by service. Mark the ones that fill up on their own and the ones that are painful to look at. It stings a little, but it heals.
2. Pick two gaps, not seven
'Weekdays' isn't a target, it's a New Year's resolution. 'Tuesday and Wednesday dinners', now that is.
3. Schedule the ads by day and hour
It's the tool we use ourselves. Ad scheduling lets you decide which days and which time slots the ads run in, and how much to bid in each one. The money that used to go out partying on Saturday night goes to work on the days you've chosen. What those adverts say when they run is in restaurant adverts: 12 examples that work.
4. Review it every week
The Tuesday that's hard to fill in April isn't the same one that's hard to fill in September. The campaign has to move with the restaurant's real calendar, not with a plan drawn up in January with great enthusiasm that nobody has opened since.
This is what the split looks like when it is done on purpose. It is a neighbourhood restaurant we manage, closed on Sundays: Tuesday and Thursday get more budget than Saturday, and the cost per action barely moves from day to day.
| Day | Spend | Actions | Cost per action |
|---|---|---|---|
| Monday | €586 | 509 | €1.15 |
| Tuesday | €778 | 654 | €1.19 |
| Wednesday | €668 | 602 | €1.11 |
| Thursday | €746 | 700 | €1.07 |
| Friday | €745 | 664 | €1.12 |
| Saturday | €740 | 665 | €1.11 |
| Monday to Saturday | €4,262 | 3,794 | €1.12 |
A case in point
At one of the restaurants we manage, we moved the budget from the weekend to Monday and Tuesday. Same investment, 31% more weekday bookings in a quarter. No magic, and not a euro more spent.
Careful, though: moving isn't switching off. The bulk of the budget always goes to the weekdays, but the weekend always keeps something. It's not about vanishing on Saturday, it's about no longer handing it all the money.
What advertising doesn't fix
A Tuesday with the kitchen closed, a menu nobody fancies or a Google Business Profile that swears you're open when you're not. Ads bring people to the door. From the door inwards, it's down to you (and whoever's cooking). And what each channel does fix, from your Google listing to word of mouth, is laid out in our guide to restaurant marketing.
Frequently asked questions
Before moving the budget
Do you have to spend more to fill up on weekdays?
No. It's about moving the same budget to the days that need it. Saturday manages on its own.
Isn't it more expensive to advertise on weekdays?
A little: in the accounts we manage, around 9% more per action. But these are people who wouldn't have come on their own, which is exactly who you want.
Does it work for lunchtimes too?
Yes. Scheduling works by day and by hour: you can push only the Tuesday-to-Thursday lunchtimes and leave the rest alone.
How often is it reviewed?
Every week, with the bookings calendar in front of you.
