Welcome back to the Disney Parks Moms Panel, Dan! We truly appreciate it when guests like you return with more great questions!
Cosmic Ray's Starlight Cafe is always a fun stop in Magic Kingdom Park. The food is tasty, there is plenty of seating, and we enjoy the smooth stylings of Sonny Eclipse! I spoke to a Cast Member in
Special Diets to find an answer to your question. There will always be a vegan option at Cosmic Ray's Starlight Cafe, but they cannot guarantee it will be a Gardenburger Malibu Vegan Burger. Their suppliers may change or the supplier may change what kind of vegan burger they offer. The Cast Member's advice is if the brand of vegan burger is important, be sure to check when you arrive to see what the restaurant currently offers. You should be able to choose a side as with other meals and it should be available on a Disney Dining Plan.
Dan, thank you for visiting us again. Please let us know if you have any other questions!
Wishing you a magical vacation,
Amy H.
