There are lots of threads on this.
Best is very difficult to say given that we know nothing about you or your family...or what you are looking for.
On our May trip, we did a "big girl" trip--no character meals. Our favorites for food quality were Le Cellier, Les Chefs de France, and Coral Reef. For atmosphere, we liked 50s Prime Time and Planet Hollywood (I have a teen). They had good food and atmosphere.
I wouldn't go back to Whispering Canyon--the atmosphere was great, the food was terrible.
DD liked Teppanyaki, I prefer the Japanese steakhouse in our town.
On past trips, for character meals we love 1900 Park Fare, Chef Mickey's, and Cape May Cafe. Cape May is breakfast only, the others are breakfast and dinner. We also like Liberty Tree Tavern for character dinner.
We didn't like the Donald's Breakafastasaurus--rushed character interaction, food only average.
CS--Kringla Bakery at Norway in Epcot. For big servings, Cosmic Ray's at MK or Peppermart at Coronado Springs. We liked several of the items at SSR where we stayed. AK Tusker House and Flame Tree BBQ are great.
