If you want to go to the “real Paris”, go to Buenos Aires, Argentina.
Funny you mention that. I have had to go there for business twice, for 2 weeks total, in the last two years. My first experiences in Argentina. I commented that much of the city looked like France or Italy of the 1970s - at the ubiquitous corner cafes and coffee shops, the waiters still wear bow-ties and formal wear - although the brothel-madam Kirchner really destroyed their currency and Argentina's ability to buy any decent coffee or chocolate to serve.
I saw a video showing the ‘yute’ stealing from tourists in broad daylight——nice place to stay away from——am I glad to be old and having had the chance to see the world and America years ago when things were orderly and decent——enjoy your ‘new world’ you who have destroyed the old-—cheers
