How do you join the Red Robin birthday club?

As of August 2015, Red Robin customers can register with the Red Robin Royalty rewards program at Redrobin.com. The program includes a free birthday burger as well as other rewards and offers. Customers must provide and verify a working telephone number during registration.

Red Robin is a popular restaurant chain specializing in gourmet hamburgers. In addition to offering a free burger during the recipient's birthday month, the rewards program allows members to receive every 10th item free and are entitled to other offers as well. Customers can pick up a physical membership card in the restaurant or simply identify themselves with their registered phone number to redeem rewards.
