As someone commented here, that if you are from the US, Pizza and pasta with some ketchup thrown on top is (used to be) known as Italian....like for example, a chain restaurant called Olive Garden. Or in my neck of the woods, you could go to "Little Italy" and find that all the cooks are from central America, so much for Italian and then of course there is the "Italian steakhouse" - which I have never seen in Italy.
In Sosua, the only (and I use the word after serious due diligence), Italian restaurant ( as in what the real italians eat), used to be the restaurant run by GianLuca, a chef and an extremely convivial person, at the New Garden hotel. The restaurant space was almost always full. He later moved back to Italy and after a year or so, when he came back, he started a place called - "Beachside" in Cabarete. When I visited his restaurant 10 days back (Yes, I recently visited the DR), he was open but is considering re-locating. Like all tourist dependent business, his place will have suffered. Having said that, the location is fabulous.
I wanted to attach a few pictures but apparently I cannot.... Try out Beachside, it is not exactly cheap but it is classy as well as genuinely Italian.
