Since you mentioned International Kitchen, I'm guessing the class you were looking at was one of Paule Caillat's? It's too bad it was cancelled because they sound great. I'm hoping to take one of her full-day classes when I'm in Paris in May.
Another possibility might be a class with Françoise Meunier. Here's her web site:

Some others are mentioned on the Paris Anglo site. I'm not sure if this link will work, but if it doesn't just try
www.paris-anglo.com and look for cooking classes in the study category.

Good luck and bon appetit!
