Pete Wells, New York Times restaurant critic, and Sam Sifton, the New York Times food editor and former restaurant reviewer, explain the art of reviewing restaurants for this week's Please Explain. They'll discuss what critics look for, what they order, how they judge the food, as well as the way the New York dining landscape has changed, the influence of reviews on the success and failure of a restaurant. They'll also explain how restaurant reviewing has changed in the age of Yelp and share stories from the best and worst places where they've eaten.
