Hi Dawn,
Welcome to the Disney Parks Moms Panel and thank you for asking us a question!
I absolutely love the theming and details that you can find at
Be Our Guest Restaurant at Magic Kingdom Park. It truly is a memorable dining experience, which is why
Disney dining reservations for all meals are strongly recommended.
The answer to your question, however, depends on which meal you’d like to enjoy at this Disney dining location. Because dinner is a “fixed price” experience, you can’t simply order dessert if you dine there during dinner hours; you’ll need to pay for the entire experience/meal.
Lunch, however, is a different story because it’s a "traditional"
counter service dining location. This means that you can absolutely only order a single meal or only dessert if you choose to dine there. You will, however, still need a dining reservation, even during the lunch and breakfast hours.
I hope my answer helps you plan a delicious Disney Parks vacation. Please don’t hesitate to come back and see us if you have any other questions.
Have a Magical Day,
Lynne
