There is uniform espresso at every corner, with quite dark roasts that cover up potential differences in flavor for the beans/crops. That's a side effect of expecting coffee for ~1 Euro, regardless of quality: quality generally goes down. We Italians are used to that (you could say we don't know better), and dislike any variation from the norm, so that doesn't bother most people; in actual coffee countries you have places that do care about coffee quality and experiment with single-origin, different roasts, etc. In Italy these places are a tiny minority, and for the rest is the same burnt expresso everywhere (and, if you're unlucky, very acid).
It might be different in big cities like Milan, but I doubt it.
