Just to balance the article, I'm french, living in Paris, working near Champs Elysées and never heard about tacos. It seems to be very specific to teenagers or ghettos.
You know, this kind of attitude is what makes people dislike Parisians.
Tossing "and from the ghettos" in there just lands him absurdly right in the middle of the shitty parisian that everyone hates.
I've never tried it myself, they look disgusting. I probably would have, if I was younger...
