You need to activate Dining Dough cards and certificates online at Dining-Dough.com before using them. After that, you can use the certificates to pay for meals at restaurants. Dining Dough maintains an online directory of participating restaurants.
To activate a Dining Dough gift card or certificate, enter the code printed on the certificate at Dining-Dough.com. Specify a restaurant after entering the code, as unspecified certificates are invalid. Participating restaurants change regularly, so check back if you are not able to find a particular restaurant. You cannot combine multiple codes into one certificate and you can only use one certificate per restaurant.
