Just to clearify...
The list I posted is a direct copy/paste from Cast Portal, and was verified with the list in DRC's information database (lovingly known as Folios.)
Officially these are the only items included as snacks, however, each restaurant/snack location is free to add additional items at their own discretion. Look for the DDP logo for additional snack items on the posted menu for additional options. I am not stating the above information is wrong, just not official. Please note in my post that I do state, "currently" as all Disney offerings are subject to change without notice.
Also, please note, many here consider me as an official source, I am a DRC Cast, but do this on my own. I just like you guys and gals :wave:. As such, I always verify my answers from official informational sources that has been cleared for release to Guests. As I value my career at Disney, I can not and will not post any pending, rumored, or proprietary information. I do sincerely hope everyone understands.
Hope this helps! :sohappy:
