Le Congres is a typical brasserie and is conveniently located in front of the Porte Maillot station close to many hotels and the big convention center. They have all the typical fare you would find at any brasserie. They are also open late until 2am.
Make sure to check out the all inclusive 36 euro business meal, which comes with a starter drink, bread basket, appetiser, main entree, cheese platter, dessert, coffee/expresso, and bottle of wine and bottled water. A great value!

This place has a lot of great dishes to choose from. I always get the steak frites when I go here. Highly recommend!
