"When we lived in Geneva, there was a famous restaurant that only served one thing: entrecote. Also known as steak-frites, it’s thin-sliced hanger steak cooked to order, covered in the most addictive herb butter sauce I’ve ever had. People literally line up out the door every night to get in–and this is why.
After playing with several bloggers’ guesses about the sauce ingredients, including some that involved chicken livers, this combination came pretty darn close to our memory of the experience. Serve with shoestring fries."
