@vonny,
I find no reason for the artistic stuff on top. I want the coffee and that's all I want it to be. Of course since my coffee is 99% of the time taken black, it would probably be unwise and maybe unsanitary if any decorating appeared.
Besides which, once you start to drink the beverage, the design disappears.
Besides which2, I always stir the coffee before doing anything else. Not sure why, I just do.
Lastly, I haven't been to Italy recently, in truth I haven't been to Italy ever...unless Little Italy counts.
