If you can get the video into a digital form (preferably MPEG), you can upload it here so people can share the moment and at least see what the hot chocolate at Angelina's is like. If you look at my blog post of my trip to Paris you'll see a picture I took of my Angelina hot chocolate experience.
Welcome to The Chocolate Life. Ahhh ... Paris. I have a picture of me with my family in almost exactly that spot. I know what you mean about Angelina, but did you ever try the chocolat chaud at la Charlotte de l'Isle? Might be even better ... but that's for you to decide. Like you need another excuse to go to Paris.
