Dubbed "the hostess with the mostest" by Zagats, Donatella Arpaia is a ubiquitous and striking presence on the national food scene. Literally raised in the business, she knows precisely what makes a guest feel welcome, whether in one of her wildly popular restaurants or one-on-one in her home. Yet every day she meets would-be home cooksβsophisticated, confident, successful women with discriminating palatesβwhose confidence evaporates at the kitchen door.
