Hello Ashley!
Welcome to the Disney Parks Moms Panel. I am thrilled you stopped by to talk about my favorite Disney topic: FOOD!
Be Our Guest Restaurant is one of my families favorite spots to enjoy a meal. The inside of the Beast's Castle is simply beautiful and I could spend hours exploring every corner of this stunning establishment. I hope you enjoy your meal.
Currently there is not a set dress code for Be Our Guest Restaurant, as long as your attire falls within the
Theme Park guidelines you will have no problems. I have seen Guests dress up for special occasions such as anniversaries or birthdays, and I have also enjoyed a meal in my shorts, tank top and tennis shoes. You won't have a problem wearing anything as long as it is family friendly and follows the guidelines highlighted in the above link.
I hope you have a magical visit. Please stop by again with any other questions you may have. If not, I invite you to sit back, and relax as Walt Disney World proudly presents your vacation.
Dream as Dreamers Do,
Jen
