Hi there, An!
Thanks so much for stopping by the Moms Panel with your great question! I'm really glad that you sent this question in because it's important to know these kinds of details.
Be Our Guest Restaurant is a fantastic place to dine for their
Quick Service lunch and
Table Service dinner. At lunch time, you can walk through the different rooms of Beast's castle as you go through the different stages of the "queue" while waiting to place your order. At dinner time, you'll be seated by a Cast Member and taken directly to a table, but you're able to walk around the restaurant and look around.
Unfortunately, the restaurant is not designed as a walk-through Attraction for Guests who are not dining there. I will tell you though, I have had the pleasure of dining at this location for both lunch and dinner, and I have to encourage you to give it a try. It's such an enchanting experience and the food is delicious!
Please let us know if we can help with any other questions you have, An!
Wishing you and your family a Pixie Dusted vacation!
