Pompeii is such an amazing archaeological site as it was frozen in time. Nor gradual decline. It really shows how the little things stay the same throughout history. From humor, to in this case, the presence of street food. I don't think there is any city we have found that is so preserved in time as Pompeii.
Unless you were an elite with a domus and slaves to tend to it, you didn't have your own kitchen. Romans in urban areas lived in apartment-style insulae that did not have individual kitchens and would either have their raw ingredients cooked at a place like this or just bought cooked food. Pompeii is dope.
Reject modernity, embrace tradition, eat every meal at McDonald's and Chick-fil-A.
