I finally wandered into Rue St Jacques for a late dinner last night. I clearly waited too long.
Mixed green salad was fresh, local and delicious. Dressing complimented, rather than overpowered. Roquefort toast elevated the dish.
Steak tartare was spiced nicely. Good flavor, although the texture seemed a bit odd to me, more dense than I recall. They were kind enough to adjust the portion size for an entree. Braised lamb shank was outstanding. Flintstonian proportion served in an iron skillet. Cooked long enough to be fork tender, but with a really nice charred crust. Polenta, braised fennel, and a generous pool of reduced red wine sauce. I tasted a bit of the chicken, it was really good, enough jus to give off nice big flavor.
To me, this is not awe inspiring food, but I don't expect that from a French bistro. However, I could only wish every meal I've ever eaten in Paris was as good as this.
