I don't think you're going to get authentic Italian food unless you got an Italian plug.
Mad tourists go to Italy and most of those tourists are American cacs.
I suspect that most of the restaurants that your average suburban cac would get led to sells food that's dumbed down for a dumbed down American cac palate.
Not to mention all the bullshyt dietary restrictions Americans love to have (vegan, gluten-free, peanut allergy, organic, wheat pasta only, pink sea salt only, "what kind of oil is it cooked in?") pretty much ruins any authentic ethnic cuisine
I ate at restaurants in Sicily, Florence, and Venice. That shyt was wack as fukk.
The food wasn't nasty, but there was just nothing special about it at all.
All of those restaurants were in areas flooded with American tourists, so I think that was the problem.
