poutine

I was surprised to learn that the French spell [Czar] Putin, Poutine, but it makes sense -- there's no official Roman alphabet spelling of the name, only a Cyrillic one, so better to avoid the possibility of mispronouncing it as "poutain."  When I saw the word "poutine" I thought I remembered it being offered to kitchen staff in a resto I worked in.  It was French fries with brown gravy and I thought I was told it's from New Orleans.  I just looked it up and it comes from Quebec.  I wouldn't be surprised if it is found in New Orleans.  Is it found in France?  merci d'avance
