Café de Paris sauce

Café de Paris sauce is a butter-based sauce served with grilled beef. When it is served with the sliced portion of an entrecôte (in American English: a rib eye steak) or a faux-filet (in English: a sirloin steak) the resulting dish is known as "entrecôte Café de Paris".

The sauce is named after the restaurant where it was created, the Café de Paris in Geneva, Switzerland.
