Graced with one of the most mesmerizing Belle Époque rooms in town -- accidentally rediscovered during renovations in the 1970s -- this is a favorite haunt of French celebrities, who adore the sunflowers, peacocks, and dragonflies of the Art Nouveau mosaic and stained-glass mise-en-scène. The menu rolls out a solid, updated classic cuisine. Try the snails in puff pastry, saddle of lamb with choron (a tomato-spiked béarnaise sauce), and bitter-chocolate fondant -- but ignore the rather depressing prix-fixe unless you're on a budget. Popular with tourists and businesspeople at lunch, La Fermette becomes truly animated around 9 PM. Métro: Franklin-D.-Roosevelt.
