Current fave Chez Janou is about 15 mins away.  We drop in when we are on the way to the movies near Bastille.  The atmosphere is very homey and inviting, warm buttery lighting and a casual low-key vibe.  Food is excellent, of course.  As the French would say, it's a "good, honest bistro."  Had dinner there last week with my good friend Fleur and her Parisian friend Emilie (who also loves Janou).  Amazing ratatouille, duck, spinach salad with goat cheese, braised lamb, grilled tuna, a nice house red and the best chocolate mousse ever.  Damn, I'm getting hungry.
