My favorites are Boma and the Wave. Used to love Captains Grille too but they are no more sadly. Maybe the new restaurant they are opening up in its place will be just as good.
The Wave!!
With a caveat!! Would not think it would be the best with children, but definitely for adults - more classy than most buffets there. Also can order from the menu.
The Wave. I wouldn't rate any of the other Disney buffets that high since they aren't great quality. Trying California Grill brunch this coming trip and looking forward to it.
