Dining Reservations – Frequently Asked Questions
Q.
Can I order my food using the My Disney Experience app or your website?
A.
Yes. There are 2 different ways to order some meals in advance at Walt Disney World Resort—you can use Mobile Food and Beverage Ordering on the
My Disney Experience app at select quick-service restaurants or use Order Ahead on our website for breakfast and lunch at
Be Our Guest Restaurant.
Mobile Food and Beverage Ordering
You can avoid the line to order and pay at select quick-service restaurants by using the My Disney Experience app on your mobile device. Guests can also use their
Disney dining plan to make a mobile order purchase.

Order Ahead
You can order ahead for breakfast or lunch—but not dinner—on disneyworld.com if you have a reservation for
Be Our Guest Restaurant—up to 30 days in advance!
To make your meal selection, go to the
My Reservations page. Starting 30 days before your reservation date, a link will appear next to your reservation. Select the link to view and choose food and beverages from the breakfast or lunch menu, then submit your order. You don’t have to pay until you arrive at the restaurant!
The amount shown on your advance order does not include tax or gratuity. For your convenience, you can pay using your credit or debit card, Disney Gift Card or cash—and with Order Ahead, you can also use your dining plan meals.
