Myself and a friend are running the Paris marathon in April and want to reward ourselves with the best steak frites in Paris that night! I have searched the boards and am still confused. We would like a restaurant with a good atmosphere, are happy to travel anywhere in Paris and will be with our wives. We are not confined by budget for the occasion and I know that while running the 26 miles, the thought of a well marbled striploin with good fries and something like a chocolate fondant with vanilla icecream will make the run that much easier to get though. I see loads of options but the fact that so many close on a Sunday night is the problem. My tentative pick so far is somewhere like Le Violon d'Ingres, which I know is not necessarily a steak frites restaurant but it looks like a nice restaurant and seems to be open on Sunday night. Is Le Relais de L'Entrecote a reliable steak house - think in also opens on Sunday night
Any help appreciated - its an important motivation!
