Hi there, Brenda!
Garden Grove, located in the Walt Disney World Swan Hotel, is definitely a delicious choice for meals.
You are welcome to order anything you like from the menu. You are by no means required to purchase the buffet.
However, according to the sample menus posted on the official Web site, la carte meals are offered during the character breakfast. Currently, no a la carte options are on the menu for dinner; you might want to call the restaurant to confirm that there will be items to your liking available to order.
Don't forget to make your reservations in advance by calling (407) WDW-DINE.
Have a wonderful time!
See you later, celebrator,
-Deborah B.
