Walking into the wide, spacious dining room at Kefi is like taking a breath of fresh ocean air. This Greek taverna, located on Columbus Avenue on the Upper West Side, is the work of Donatella Arpaia and Executive Chef Michael Psilakis, Bon Appetit's Chef of the Year in 2008, and the recipient of a long list of accolades from The New York Times to James Beard. Kefi means the bliss that accompanies drunken revelry, and the menu sings with signature dishes including the grilled octopus and tsoutsoukaki, otherwise known as the best meatballs in NYC by NY Mag in 2007.
