McDonald’s Australia style: Why can’t they do this in the USA?

The McDonald’s closest to the part of the University of Sydney where I am working temporarily, looks like no McDonald’s I’ve ever seen.

Under The Corner, it says McCafe.  This place is a Maccas, as they call them here.

The Corner offers an acceptable salad bar.

And slogans:

An improvement?  Yes, but why not in the U.S.?
