Nothing can compare to the incomparable view & live music enjoyed at the CA Grill brunch.
It was the most humane meal we have ever enjoyed with our child (since she is still too young for Victoria & Albert) at Disney. It was repeatedly the best food we have ever had at CA Grill (I never seem to enjoy their dinner menu).
Waldorf, Ritz Carlton, & Four Seasons are all in the vicinity. While I have no first-hand experience, it seems to me as if the grand hotel-style buffet brunch at Ravello is the closest to that quality hotel breakfast that could compare to CA Grill.
Similarly, Amare just opened in Swan Reserve. They have a $36 buffet brunch. I know nothing else about the food or space.
But nothing is really gonna' compare because CA Grill brunch was too much food (and worth every penny of the cost).
Also, a quick internet search should get you lists of plenty of places that serve high-quality breakfasts, but I don't think any have the impressive grandeur of a large hotel dining space.
