I have been to Angelina http://www.angelina.fr and their chocolate is really heavenly. They serve it in a silver tray, with a mug of hot chocolate (enough for 2 and a half cups) and some creme-fraiche. It´s quite thick (more similar to a good spanish chocolate), not like the milky hot chocolate served in other places in Europe.

Another place I like is the Cafe Marly in the Louvre. It´s one of the cafes at the museum, but you don´t need to go inside. I had never been there before until last October, and although a bit expensive, I thought that it wasn´t so bad, given the service (the people from Costes) and the place. http://www.paris.org/Cafes/marly.html
