These are very good places that are as expensive as #1. Within a block of the Ren. is this wonderful place. Very reasonable, very friendly.
Just a block or so away from the Marriott C-E, is a great local place for frog legs.
For great Parisian steak, go with both of these, they are within walking distance of the Marriott C-E. Only steak on the menu, but it is great at both places! Cafe de la Paix, is one of my favorites, just across the street from the Opera, it is a great place to dine and people watch.
