Below is a comprehensive summary based on available information from consumer websites and deal blogs.

The Smashburger Birthday Freebie Offer

Based on the provided source documents, Smashburger offers birthday rewards to members of its loyalty program. There appears to be some variation in what exactly is offered:

Free Shake: The most commonly mentioned birthday freebie across multiple sources is a free shake.

Free Side and/or Classic Smash Burger: Source 6 indicates "SmashClub members receive a free side and/or classic smash burger on their birthday."

The value of these free items appears to be consistent with the restaurant's regular menu pricing, though specific values are not mentioned in the source documents.

When the Offer is Available

Most sources do not specify the exact timeframe during which the birthday freebie can be redeemed. However, Source 5 notes that birthday promotions "may last your whole birthday month and others may be good for up to 14 days after your birthday."
