Sorry, I was NOT referring to South Philly in my post - but indeed someone else here confirmed my observation in some other geography.
I also am speaking as someone who lived in the EU for a long time and so my "Italian" is different from those that had Italian in the US. This is not to say that the Italian food in the US is not better than what it once was but, barring high class NY restaurant (I know nothing of CA and if I am in LA, I would go only to the Japanese Sashimi places), Italian food in the US is unrepresentative, first because historically it was food of the poor immigrants from the South, second because of US fascination with quantity (bigger portion is better and we can see the impact of that all around us) and finally, because it had to adjust to the local taste - the people of English/Scottish stock had only boiled stuff, which I enjoy during my NZ trips at English immigrants' residences, who maintain their own tradition there.
Italian food, whether from North or South is way superior - from a fish baked in oven, submerged inside nothing but sea salt in Genoa, to Orechhiette con cime de rapa in Bari. In the DR, I find better Italian food, a) because the restaurants I frequent are owned by the expat Italians, for example in Boca Chica/SD and b) there is a lot of genuine Italian ingredients available - some of which are not allowed into the US - for example someone mentioned "pancetta".
My favorite restaurant in Cabarete is my favorite, also because and this is fairly rare, that the Chef himself is Italian and not being from the South, has a different culinary footprint. In fact, the original owner of the Bologna restaurant was/is from Bologna and the food used to be excellent before it got sold off. By the way, I find the German and French restaurants around the North Coast to be very good too, again for similar reasons. I mean I found reibekuchen at a beachside place in Sosua - unthinkable!
