Denny’s free birthday offer is a free Grand Slam breakfast. The offer is only valid on the day of your birthday, as opposed to the entire week like some restaurants, so no dilly dallying! You have permission to dilly though. There’s always time to dilly.
Signup Freebie: 20% off entire guest check.
Birthday Freebie: Free Grand Slam breakfast.
Remember, we have a full list of free birthday food!
