I don't know what fancy shmancy hotels offer for breakfast, because I'm a cheap ass and stay at mid-priced/budget hotels on road trips. This means mostly bare bones continental stuff or nothing at all, except coffee...which irks me, since I'm not a coffee drinker.
But sometimes, there's good stuff! Like omelettes, and biscuits and gravy....
....and yogurt and bagels and bananas, which are awesome for amusement purposes, when bored. :)
