Chris and I recently ventured to Mon Ami Gabi in Bethesda for its Restaurant Week. If you've never been there, Mon Ami Gabi serves classic French cuisine and everything about it is enjoyable. We started with Baked Cheese, which is goat cheese baked in tomato sauce served with buttered baguette crisps. Even though I'm not usually a fan of goat cheese, I was even craving this a few days afterwards. Our entree was the classic Steak Frites, a wonderful hangar steak served with French fries. For dessert, we had chocolate lava cake with ice cream (in the picture above).
The DC area has two locations, one in Bethesda and the other in Reston. If you're looking for a nice date night place, Mon Ami Gabi is a must.
