Since I don't hit the parks at 7:00 am, can't answer your question
But, have seen very short lines at the restaurant at 8:45 am
Many do the place early so they can do rides as lower ride lines then
I prefer to do that place at 10:30 as they start lunch menu then and breakfast hour still available to 11:00
That crossover period has low crowds then
Not fond of the breakfast menu but love the lunch menu
