There are so many options for good food in the parks and resorts!
In the parks for Table Service...
MK: The Plaza, Super easy to get reservations to and super cool atmosphere i don't think that many people like it or know about it but its one of my favorites
Epcot: This ones a tie for me Tutto Italia, Chefs De France, or La Hacienda de San Angel. All three are great options but just look at the menu and see what speaks to you
HS: Sci-Fi Diner, If you are traveling with kids i would definitely recommend this you eat in an old fashion car and watch movies super cool and good food too
AK: Yak and Yeti, When you walk into Yak and yeti you don't feel like your in a theme park! The food is really good too, but if you have picky eaters check the kids menu first
Parks Counter Service...
MK:Columbia Harbor House, This place has super good food! It is always a good option
Epcot: Sunshine Seasons, My favorite cs in the parks because of the wide variety of healthier options that taste delicious, also they have really good dessert options
HS: I am not a big fan of any CS restaurants in HS, ABC Comminsary is fine at best but they have been getting their act together.
AK: Satulli Canteen, Great options for everyone, but especially kids. Always have had a good experience there
Resorts Counter Service...
Contempo Cafe, Contempery - Right next to the magic kingdom and probably my favorite counter service at WDW look at the menu there stuff for everyone
The Mara, AKL - Super delicious CS restaurant with healthy options, check the menu first because some dishes are African themed
I hope this will help you for your trip. I hope you have a magical time!
