we four went on 9-6-06 and the construction on their side of the street (subway ventilation improvements) is gone, yay, after many years. The place was packed, but, as always, we were seated promptly and mussels, vichysoise (an interesting dark color with a wonderful taste), frites and etc were all excellent. Try the napoleon of beteraves, a beet salad with four different kinds of beets stacked on layers of chevre. The fastest response time between a drink order and the drink I have ever seen - it is as if the drink has been waiting for you. Unheralded aspects are the architectural details embedded in the walls and the superb photographs hung there.
Pros: ambience, attentive service, interesting food well explained
