My favorite meal in Paris was at L'Entrecote. After reading mixed reviews on TripAdvisor I debated trying this restaurant... good thing I don't listen to reviews. Because in my opinion their World Famous Sauce was one of my best encounters in Paris... which tasted like a gourmet blend of mustard and butter; heaven on their traditional seared medium rare to rare tenderloin beef which is kept heated at your table. Though the fries were perfectly crisp, the ones that were smothered in sauce were oh so good. I'm going to have to try to replicate this sauce at home. They even brought me a second serving of it after witnessing me scraping every last bit, and it was comforting to see many 'business lunchers' rather than tourists when I went.
