I actually had a very similar experience nearby in Lucca, not far from Florence and Pisa. Only it was tomatoes in the pizza sauce. It was amazing, but have no recollection of the name of the restaurant.
My best experience in an italian restaurant was in a small fishermen restaurant in Conca dei Marini. Shit was kind of lost in the middle of nowhere, I don't even think it had a name. But it was the most delicious meal on my whole trip. Chef kiss
Oh if you find it on google please post it. I am intrigued. My dream is to retire near there one day. I’ve been bookmarking all my favorite places along the coast there.
Here’s my favorite little locals seafood joint near Sorrento:

It might have been any one of the three restaurants on the map there, considering how things are done on Italy, all three might be runned by the very same family, just different brothers.
I remember being served an unordered wheel of bread with lots of tomato sauce 'on the house', it was amazing, no other restaurant in Florence, Rome or Venice offered something similar.
Totally recommend askibg for limoncello as a dessert, it blew our minds.
Having traveled quite a bit in Mexico, Belize, and Guatemala, those hole in the wall restaurants are just THE BEST. And you can usually tell when it's the owners running it themselves. Compliments go a long way in those places and by god do they almost always have amazing food.
