Rest assured that there is a little something for both foodie types and meat-and-potato diners at Walt Disney World, Tammy. The
Yachtsman Steakhouse, for instance, offers filet mignon with straight up mashed potatoes. Another option would be the
Whispering Canyon Cafe at Disney's Wilderness Lodge, where a New York Strip served with canyon fries and garden vegetables in on the menu. The
50's Prime Time Cafe at Hollywood Studios offers a traditional meatloaf with a side of mashed potatoes (horseradish free!). And if you dine elsewhere, do ask whether a plain baked potato is available as a side, even if it's not on the menu; some restaurants may be able to accommodate your request.
I think you'll find plenty of menu items to choose from that will suit your eating style. Hamburgers, chicken strips and pizzas can also be readily found across property. I hope you enjoy both the trip and the food!
