Hi @Aesthete,
BBQ? No? But I (nor any of my friends (some who’ve been to Italy)) have experienced “BBQ Sauce Pasta” before. I’m glad you like that flavor, but all of us at the table found it offputting / strange. It’s not “gross” of course, but it’s like eating, say, American BBQ Sauce Chow Mein or something. Do some people find it exciting and different? Perhaps? It’s just not for me.
It was strange because the other sauces all tasted and connoted flavors we’ve run across at many Italian places (and purer in some ways), but not that one.
Well their Costata Alla Fiorentina was explicitly stated by our server as “way too much” food. It was recommended to share with “at least 4 - 5 people” is what she said. She never gave us the breakdown of how heavy the bone was (or if it was bone-in). So I’m just going by what our server recommended to us. Price? I was going to ask, but since it was a non-starter, I didn’t follow-up.
No, I haven’t been to Italy, but our guest had. I’ve tried a variety of Cacio e Pepe from various recommended Italian eateries around the U.S. and Canada. I never said their Cacio e Pepe was “inauthentic” nor did I imply that. I said it felt “tame” which my friend who has been to Italy agreed (just getting their impressions), and my own from a variety of places I’ve tried over the years.
And note that the Pesto examples I brought up are from actual Italian natives, from Italy (not like Chef Funke who’s only traveled there and studied a bit, not his whole life)? Leo Bulagarini’s Pesto is far more vibrant, pure, and interesting than Felix’s version. Same for the Pesto I had at Pasta Sisters from Paola Da Re and her family. Their Pesto was also just more interesting to me, but your mileage may vary. 
Lastly, for the Pizza, that’s good to know. When Attilio Bachetti from Pizzeria Da Attilio in Naples, Italy was doing his pop-up at DeSano, all of his pies were served cut. He seemed pretty authentic to me, and maybe he conformed to a recommendation from the DeSano staff, but he had no issues doing it for his masterpieces (and they were that wonderful), and it didn’t take away from the pies.
Sometimes it’s nice to incorporate innovations or changes that make the dining experience more enjoyable. In this case, it feels like the pies wouldn’t have suffered having them pre-cut; it just adds to the frustration when it’s uncut IMHO. But I did note that it’s far better than what other places do, and that’s provide an actual extremely sharp knife to cut the pie with.
Thanks.
