Expensive breakfasts have been hit or miss in my experience. Occasionally, it is readily apparent that they are making everything in house by the taste and texture. Quite often, it is equally clear that they are buying in lots of things pre-made. I like eggs benedict when I go to a nicer place for breakfast. Something as simple as a poached egg seems to really mess up a lot of restaurants. Hollandaise is another tough one for some reason.

Cheap breakfast can be just as good or bad. For example, in the US south, a plate of scratch made biscuits and gravy will be delicious and cheap.
