Mystery Diners Service Fees

Quick Summary: For restaurants that join the Mystery Diner Service during the pre-launch and 30 days that follow, each Mystery Diner visit (or MDA) fee will be £5.

Each MDA is reserved by a Mystery Diner for which they will receive a £15 Off food and drink COUPON that the restaurant will accept against the MD bill or account.

Mystery Diners provide 3 reviews for each MDA so restaurants will receive 60 reviews each month they participate. For the full calculation that explains see below.

As soon as a restaurant is promoted to Mystery Diners we expect 3 to 5 couples to reserve and complete assignments within 10 days to generate 18 and 30 reviews.

The £60 setup fee will be invoiced 7 days after assignments are offered to Mystery Diners and be payable after another 7 days i.e. payment will be due after 14 days.

Fees for Mystery Diners and Assignments are invoiced upon their completion and payable before the following month of MDAs are offered to the next group of MDs.

Mystery Diners FAQ's

Are assignments always for two Mystery Diners?

Most assignments are for 'mystery diners' couples as it's important they remain incognito until it comes to paying the bill. From time to time special assignments we require larger groups and singles.

Will members receive unwanted or spam/junk emails?

Our strict privacy policy adheres to the GDPR regulations, in fact it goes one step further. dooZza will not send emails for any other purpose than to keep members informed about the services offered. You may have noticed we do NOT ask for specific home address details in any of our forms.

What is the value of the Mystery Diner Coupons?

Each 'mystery diner' coupon has an exchange value of £15, so a couple will receive £30 off the total bill on assignments. If the bill is greater than £30 then the mystery diners are responsible for the extra, which must be settled at the time of the assignment.
