Hello there Ashley, and welcome to planDisney! We're so glad you're here!
Galactic Grill in Tomorrowland in
Disneyland Park is a great place to blast off for a meal at the parks! I'm not sure how old your little sister is or how big her appetite is, but my son who has a larger appetite still orders from the kids menu. The
kids hamburger is definitely smaller than the adult portion, but it also comes with a yogurt smoothie and a mandarin orange as well as a milk or small bottle of water. If my son was extra hungry that day I may consider ordering the adult portion, but usually the kids meal is the perfect size! I'm sure you could ask a friendly cast member at Galactic Grill to take a peek at the portion size before ordering as well.
A great way to help save money throughout the parks is bringing in your own snacks which we do every trip. We've found that the snacks can tide us over until our next meal, and help save some money throughout the week. Also, some of our favorite Disney snacks such as the
popcorn you can find at the popcorn carts throughout the parks as well as the
Mickey-shaped pretzel you can find at the pretzel carts are a great deal and much cheaper than other snack options!
I hope this information about Galactic Grill was useful for your planning Ashley. If you have any other questions as you prepare for your trip,
please come back and ask!
Have a magical day!
Melissa
