When staying at the Biltmore we went with the breakfast inclusive package while, as the name suggests, includes breakfast. If you decide to include this option then you will have a note in your room listing where you can eat your breakfast. For us, our options were:
Fontana (Breakfast Buffet Only)
Monday to Saturday from 7AM to 11AM
Sundays from 7AM to 9AM
the 19th hole (A la carte)
Sundays from 8AM to 11AM
Cascade (A la carte)
Sundays from 7AM to 11AM
It did not include room service or the Sunday brunch.
As we were staying at the hotel on a Sunday night our breakfast would be the Fontana breakfast buffet on the Monday morning. We got up and headed down where we were quickly sat at a table near the breakfast buffet. Freshly squeezed juice (orange, grapefruit, or apple) , coffee, and tea were served to us by the wait staff. The buffet was not very large but it had something for everyone. It was all laid out on the bar top in a single line that started with a selection of pastries and bread then cereal followed by the hot items which included bacon, scrambled eggs, hash browns, and pancakes. Then at the end of the line was various fresh fruit, chesses, and sandwich meats.
We didn't feel that it was worth paying for but supposedly the Sunday Brunch is one of the bests in the area and not something to be missed.
Keep in mind that COVID may change things up.
