Key takeaways
- Ask few questions, ask them at the right moment and make it easy to answer in under a minute.
- Google's policy bans paid or incentivised reviews and selectively soliciting positive ones, so keep private feedback and public reviews honest and separate in purpose.
- Collect only the personal data you need, say how you will use it and delete it when you are done.
- Feedback is only worth collecting if someone reads it weekly, fixes what repeats and tells the team what changed.
In short: ask a few good questions at the right moment, make it effortless, read the answers every week and change something visible. Keep private feedback honest and separate from public reviews, never offer rewards for Google reviews and never steer only happy guests to them. Collect the minimum personal data.

Most guests never tell you what they thought. They either say "lovely, thanks" on the way out or they say nothing and do not come back. A small number post a public review. If you rely on those, you hear mostly the extremes.
Good feedback collection gives you the quiet middle: what worked, what was a little off, what nearly made them leave. It is cheap, fast and one of the best sources of improvement ideas. It is also easy to do badly, with long forms nobody answers and results nobody reads.
Decide what you want to learn
Start with a question you want to answer. For example:
- Is the food arriving hot, and how long are guests waiting?
- Do guests feel looked after?
- Is the room comfortable, clean and quiet enough?
- Is the menu clear? Do guests find what they want?
- Was online ordering or delivery easy?
- Would they come back, and would they recommend us?
Pick two or three themes for the month and write questions for them. Rotate themes so the survey stays short.
Write a short survey
A good restaurant survey is five questions or fewer.
- A simple rating of the visit, on a scale that is easy to understand, such as one to five.
- One topic question: "How was the speed of service?" or "How was the food temperature?"
- One open question: "What is one thing we could do better?"
- Optional: "May we contact you about your comment?" with a field for a phone number or an email address.
- Optional: "What was the occasion?" if it helps you plan.
Tips:
- Use plain words and avoid leading questions. "How was your wonderful meal?" is not a question.
- Keep the scale the same each time so you can compare.
- Make the open question the most prominent: it contains the real answers.
- Avoid asking for information you already have, such as table number or date.
- Offer the survey in the languages your guests speak.
Choose the moment and the channel
| Channel | Best for | Watch out for |
|---|---|---|
| Table card with a QR code | Dine in, at the bill | Guests may not scan; keep the form short and mobile friendly |
| Printed card or comment slip | Older guests, relaxed meals | Needs a box, and someone to type them up |
| A word from the manager at the table | Real time fixes | Guests may be polite rather than honest |
| Receipt or order confirmation link | Takeaway and online orders | Only people who click answer |
| A short message after the visit | Reservations with a phone number or email | Marketing and privacy rules; keep it short and send once |
| Delivery follow up | Delivery quality and timing | Ask after the order should have arrived |
| In app or on your own site | Guests using your own ordering | Keep it optional |
DineHarbor includes guest reviews as part of its feature set, and you can also run a short survey with any tool you prefer. What matters is that the feedback reaches one person who reads it.
Real time recovery beats a perfect survey
The best moment to fix a problem is while the guest is still in the room. Train servers and managers to notice and ask: "How is everything?" is weak, "How is the steak cooked?" is better. A manager walking the floor in the first half of service catches issues before they become one star reviews. See great service basics and reviews and complaints.
Keep private feedback and public reviews honest
Google's rules matter here. According to Google's policy on prohibited and restricted content:
- Fake engagement is not allowed and will be removed. Examples include reviews or ratings that have been paid for, directly or in kind.
- Rating manipulation includes incentivised or biased reviews, which are not allowed and will be removed from Maps.
- Merchants may not offer payment, discounts or free goods or services in exchange for a review, a revision of one or the removal of a negative one.
- Merchants may not "discourage or prohibit negative reviews, or selectively solicit positive reviews from customers".
- Merchants may still solicit or encourage the posting of content that represents a genuine experience, as long as they offer no incentive and do not try to influence the rating or the wording.
In practice, this means:
- Never offer a discount, a free drink or a prize for a Google review. A prize draw for survey respondents is a separate matter if it is not tied to posting a public review, but keep the two apart and check your local rules on promotions.
- Do not run a "happy or not" gate that sends high scorers to Google and low scorers to a private form. Ask every guest the same way.
- Do ask, in a neutral way, if guests are willing to share their genuine experience, for example with a QR code on a card.
- Do not pressure guests or ask staff to ask only for good ratings.
- Do not write or buy reviews.

Privacy and messages
Any survey that asks for a name, phone number or email collects personal data.
- Collect only what you need. The UK ICO describes data minimisation as holding data limited to what is necessary for your purpose, and storage limitation as keeping identifiable data for no longer than necessary. If you do not need to contact the guest, make the contact field optional or leave it out.
- Say what you will do with it: "We will only use your number to reply to your comment."
- Keep it safe and restrict who can see it.
- Delete it when the comment has been handled.
- Marketing is separate. The ICO's summary of the UK Privacy and Electronic Communications Regulations is that they restrict unsolicited direct marketing by phone, email, text and other electronic messages. A pure service message is different from a promotion, but if you add a voucher or a promotion to a survey message, treat it as marketing and check your local rules. See email and SMS marketing.
Read it, sort it, act on it
A survey is useful only if it changes something. Build a weekly routine:
- Collect the week's answers in one place, whether a spreadsheet or a shared document.
- Read every comment. It takes ten minutes.
- Tag them by theme: food, speed, service, atmosphere, cleanliness, price, online ordering, delivery.
- Count the themes. Three comments about slow desserts matter more than one comment about a favourite dish.
- Pick one or two changes for the next week. Make them small and specific.
- Tell the team what guests said and what you are changing, and give credit for praise.
- Close the loop with guests who left contact details and asked for a reply: thank them and tell them what you changed.
Use scores carefully
- Compare like with like. Weekday against weekday, lunch against lunch.
- Watch trends over four to eight weeks, not single days.
- Do not turn the scores into a staff punishment. People will game it or ask guests for good scores.
- Combine surveys with other signals such as ticket times and remakes. See KPIs.
- Be careful with small samples. Ten answers do not tell you much.
Special cases
- Delivery and takeaway. Ask about timing, temperature and accuracy. Link problems to the order. See takeaway and delivery profit.
- Events and large groups. Ask the organiser for feedback in person, and send one follow up.
- Allergy guests. Ask them about the process rather than the dish, and take any near miss seriously. See allergen training.
- Regulars. Ask them in person, in a relaxed conversation.
- Guests who complain. Do not turn the complaint into a survey. Listen first, fix and follow up.
Common mistakes
- A long form that no one finishes.
- Collecting data and never reading it.
- Offering rewards for Google reviews.
- Sending only happy guests to a public review page.
- Keeping phone numbers forever.
- Asking leading questions.
- Not telling the team what changed.
A checklist
- Pick two or three themes and write five questions or fewer.
- Choose the moments and channels that suit your guests.
- Ask everyone in the same neutral way.
- Offer no incentives for public reviews.
- Collect only the data you need and delete it after use.
- Read, tag and count every week.
- Change one or two things and tell the team.
- Reply to guests who asked for a response.

Questions and answers
How long should a restaurant survey be?
As short as possible. Three to five questions that can be answered in under a minute get more answers than a long form, and you will read all of them.
When should I ask for feedback?
Close to the visit, while it is fresh: at the table with the bill, on a receipt or by a short message the same day. For delivery and takeaway, ask after the order arrives.
Can I offer a discount for a review?
Not for a Google review. Google's policy says merchants may not offer payment, discounts or free goods or services in exchange for a review or to revise or remove one. You may ask for genuine experiences without an incentive.
Can I send only happy guests to Google?
No. Google's policy says merchants may not discourage or prohibit negative reviews or selectively solicit positive reviews. Ask everyone in the same way.
Is a feedback message a marketing message?
It depends on its purpose and on your country's rules. In the UK the ICO says electronic marketing rules restrict unsolicited direct marketing by phone, email and text. If your survey also promotes something, treat it with care and check your local rules.
