Another reason I will always love Rue de la Huchette is that it is the home of the very first Jazz club I went to.
I wish I would have gone sooner, but I'm glad I got there before I left, at least. (And barely. I went the night before I came home, just after a teaching and dinner appointment with the Sister missionaries.)
If you like music and you're visiting Paris, this was a lot of fun. (Please also note that it is item #46 of my 101 in 1001.)
