More often than not, tipsters, readers, friends and family of Eater have one question: Where should I eat right now? What are the new restaurants? What’s everyone talking about? While the Eater 18 is a crucial resource covering old standbys and neighborhood essentials across the city, it is not a chronicle of the “it” places of the moment. Enter the Eater Heatmap, which will change continually to highlight the spots crowds are flocking to at the moment. Today the map welcomes On Forty-One to the list.
