Big Daddy's Burgers in Ballantyne across from the Ballantyne Hotel serves an excellent breakfast on Saturday and Sunday mornings. I recommend the "average joe" breakfast with 3 eggs, biscuit, potatoes and bacon, plus you do not have to wait for a fashionable hour for them to open; they open at 8:00 AM on the weekends. Except for here and John's on Central not many other Charlotte restaurant know how to do an early morning breakfast.
At lunch their burgers and fries are just as good as their other spot on East Blvd.
