Mythical, inescapable, grandiose... for more than 150 years, all the grandiloquent adjectives have been used to the full to qualify this institution, where you sometimes enter simply to take a few photos, without consuming anything, before continuing your stroll in the Opéra district. The decor is magnificent, it's true, skilfully blending the original Napoleon III spirit with a few more contemporary elements. Take a seat on the terrace, overlooking the Opéra, or in the large dining room with its gold-leaf panelling, and you'll quickly realize that the weekly menu is an excellent choice, allowing you (at lunchtime and on weekdays only) to fully appreciate the spirit of the place: a good Paris-Toulouse sausage on Wednesday with its lovely mashed potatoes, a blanquette de veau riz pilaf in the rules of the art on Thursday, good steamed leeks and mimosa egg as a starter and a perfect organic vanilla millefeuille from Madagascar to conclude a deftly placed sequence at €49. The menu quickly takes you to altitudes where oxygen is scarce (count 100 euros if you're being reasonable for a starter/main course/dessert sequence), the cellar is neither very modern nor cheap and the service is more impressive for its activity than for its personality.
