Bistrot du Coin is an excellent reconstruction of a Paris bistro. In the Spring and Summer, they fling the front of the place open to the sidewalk. The place is always noisy and typically packed, though you won't have to wait too long for a table (except maybe on Saturday nights). Wonderful cheese dishes, great salads, and superb mussels in a variety of presentations, with a very respectable wine selection. Even the waiters can often seem rude, but it's only an act to make you feel like you're on the Left Bank. Highly recommended.
