The name of a city that was burned and razed more than 2,000 years ago is not one I ever expected to see on a going concern. The food, which at a glance seemed no different from that of many other halal carts, is not specific to the proprietor's homeland, he confirmed. (I didn't try it; not oversalted, let's hope.)
"Carthage," the cart man explained, is an homage to the ancient city, which in his home country (You've named it, yes?) is still a point of pride. Indeed, a dining buddy informed me, a suburb of the current capital shares the name. The styling of that capital "C" evokes the flag that flies above it.
