Yup, lots of takeout, most Romans didn’t have kitchens, partly a money problem, partly a fire risk and most were renters and their landlords and local authorities didn’t want the city to burn down.
There’s a place near here that makes regular pizzas, but also offers the Roman-era experience (doesn’t call it that), pizza crust with no tomato (the tomato being post-1492).
Best pizzas we have ever had were in Italy.
We stayed in the south, many, many moons ago, not far from Naples.
Locals always told us it was the volcanic soil that made the locally grown tomatoes taste so good.
I believe them.
We got to Pompeii a few times. I’d love to go back again.
