In the debut episode of "The Four Top," host Katherine Cole is joined by certified cicerone Lucy Burningham, eater.com reports editor Erin DeJesus and cookbook author Laura Russell. This week we talk trash about the environmental scourge du jour: food waste. Next, we unpack the baffling breakfast-ization of dinner (cereal-milk cocktails, anyone?). Finally, we test-drive the hottest dining apps for your phone. And we talk to the ghost of Prince. We really do. For dessert, we chitchat about yogurt beers, a restaurant's sidewalk-free-for-all fridge and the hot restaurant scene in Charleston, South Carolina.
