Truffle Grater is where people who trust each other's recommendations share their favorite restaurants around the world. It's a scaleable form of the most proven recommendation system: asking your friends, who are influenced by their friends. As well as the waiters and chefs at the restaurants you enjoy the most.
An endorsement means: You'd go back at chance. If your friend from out of town had a single night in the city, this is where you'd take them. Worth trekking across the city for. Worth travelling for along with your other endorsements. Good enough you don't need to tell people more than the name and address. People are accountable for their endorsements.
