A little of both.
Quieter than I've seen it at lunch or dinner, but the servers were still ready to let loose if the guests seemed ready. Most of the children who were there when we were eating were still a bit sleepy-eyed, and so there weren't any horse races.
My wife and I had one of their breakfast all-you-can-eats, and the food was standard breakfast fare (scrambled eggs, sausage, bacon, hash browns.)
