I suggest Grand Floridian Cafe for any meal.
The atmosphere is bright and cheerful, service efficient, food among the best of TS.
Even if you don't need gluten-free, the g-f apple crisp is as good as homemade, eggs benedict excellent, salmon delicious--yes, I LIKE the place. Salads are delectable, too.
It's a relaxing place to unwind after a park or simply to close out a lovely Disney day.
Also, highly recommend the open-air lounge, Geyser Point, at Wilderness Lodge. It's a bit rustic and might not be where you'd care to eat on a drizzly, chilly evening. The food could make up for any less-than-optimal weather. The bison burger description sounds quirky, but it all goes together fabulously--highly recommended.
A wonderful place for MK fireworks watching with yummy food.
