Hi Ulrikmo,
Those YouTube videos aren't mine, I just found them via baristaexchange.com discussions. The bar, Bar De.Ga, is somewhere in Napoli, and the barista's name is Rosario. Posted in 2009 by Carlo Grenci who I think may own that bar. I tried to find its exact location via googling, but no luck. I agree totally -- pilgrimage to Napoli.
