Nah I can speak from experience that both the best and worst pizza I've ever had were had within the very same visit to Rome. Probably within 24 hours of each other.

Once in an almost touristy area - not the spots with the most traffic, mind you, but where you transferred from suburban rail to bus to get to those spots, so still in the city. Hot garbage. The worst pizza I've had in my life. It was soggy, thin, and mass-produced, who knows how long it had been sitting out, served in an atmosphere I can only describe as mall cafeteria but smaller and contained in one storefront.

Best pizza was this little take-out spot in a beach district called Ostia, on the other end of that same rail line, which I stumbled upon by chance because I forgot to bring a swimsuit for the beach and it was across from the calzedonia I happened to stop at. I took it to eat with my friend who was sitting outside a nearby cafe. It was hot, crispy, with fresh tomato sauce and soft bread. I probably won't find anything that measures up to it for a while tbh.

The closest since then is maybe a small local place down the road from me here in Michigan, but I'm also someone that can appreciate american pizza for what it is. It's not trying to be italian and that's okay lol.

I had other pizza in Rome too but honestly most of the food I had there, save that one slice from the mom and pop shop in Ostia, really wasn't anything to write home about.

I remember the one in Rome, it was somewhere in a residential area, not Colloseum etc, and there was a small line of people waiting. Very likely it was a bad place or some strange style of pizza that did not hit my plebean tastebuds. Or anyone else's in our little group.
