Returning to Champs Elysees at night, we had dinner at Leon du Bruxelles, belgian cuisine. Ate a full course which consisted of grilled cheese as appetizer, a pot full of moussels, french fries, ending with a creme brulee. Here's their website: http://www.leon-de-bruxelles.fr/. Recommended to one of my colleague as well. [Leon du Bruxelles. Paris]
