My favorites
If you like buffets, The Crystal Palace(B, L, OR D) is always great. We love the characters, too.
I personally enjoyed BOMA'S breakfast buffet. They served a variety of pastries, muffins, waffles, cinnamon raisin french toast, roast ham and turkey(over an open fire pit- really cool, with a variety of sauces to try with it, fresh fruit, etc, etc,..Lots of choices and I recommend getting the LATEST breakfast reservation you can so that it's like brunch and you won't be hungry til dinner time.
I also recommend The Yak N Yeti at The Animal Kingdom. My husband had the ribs and I had the salmon. BOTH amazing, FABULOUS SERVER- he knew we were in a hurry, our food came out fast, he had our drinks full at all times and we got our desserts to go and they were exceptional.
Donald's Safari breakfast is also great- all the favorite characters, they spent alot of time at our table and were really cute with our kids. The variety is unbelievable. I was stuffed and not even hungry at dinner.
Ohana's Breakfast is great. All you can eat platters of food. Unique. The Sausage. OH my gosh. the sausage. Yummy juice. Great service.
We ate at Teppan Edo at Epcot. I thought it was ALRIGHT, but if you REALLY enjoy Japanese hibachi, you may enjoy this. The neighboring restaurant, Tokyo Dining has HIGH ratings and i have heard great things.
This September, due to ratings/reviews I have read and wanting to try something new, We will be dining at Les Chef's de France, The Rose and Crown, The Captain's Grille(at Yacht club resort), Sanaa' at The Animal Kingdom Lodge, The Sci Fi (A favorite- i know you said you didn't care for it), The Whispering Canyon Cafe', The Crystal Palace(breakfast- 1st seating so that we can get pictures in front of the castle at the end of main street with NO ONE else around- heard this is cool to do if you have never tried it), and The Plaza Restaurant at Magic Kingdom.
GOOD LUCK! I wish you the best and hope you have a Magical stay in Disney world this August.
