I seem to remember that the restaurant was called "Paris" too. Can anyone help? It was the most decadent dessert I have ever had.
There's a Café-Boulangerie Paillard in Quebec; they have a facebook page; possibly you could find out something through that. Another website, chowhound.com, has various local message boards; you might be able to reach someone with local knowledge through one of those.
And the cafe-bakery website has listing of products and illustrations of them too. Maybe they'll jog a memory.
