Hi Jamie!
Thank you for bringing your question to the Disney Parks Moms Panel. Congratulations on celebrating 10 years with your Prince Charming!
You have certainly heard correct that there are complimentary celebration buttons that you can pick up when you arrive in the park. You'll want to stop by either
City Hall in Disneyland Park or the Chamber of Commerce in Disney California Adventure Park and let them know that you are celebrating a milestone anniversary. The friendly Cast Member assisting you will give you and your hubby matching buttons for you to proudly sport during your trip!
For a romantic dinner there are two places that immediately come to mind. The first would be
Blue Bayou Restaurant inside New Orleans Square at Disneyland Park. This restaurant is actually set inside of The Pirates of the Caribbean attraction, but you'll feel like you are sitting on a New Orleans bayou in the evening with the dark atmosphere and soft crickets chirping. My recommendation for Disney California Adventure Park would be
Carthay Circle Restaurant. This is certainly a romantic atmosphere that celebrates the glamour of old Hollywood. I'd peruse over the menu for both and see which sounds better for y'all! Both of these restaurants will require a reservation, which will open up 60 days before your arrival. For a popular dining time, I'd try and make your reservation as early as you can.
Once again congratulations and please let us know if we can help you plan your trip in any other way!
