I had been anxiously awaiting the opening of Lumière Chef Michael Levitan’s new restaurant “concept,” Area Four. Never having ventured to the Chef’s “project”, Persephone, during its single year of service to hungry hipsters and haute-couturists, I had nothing to gauge the potential success of the Leviton-Krupps partnership. Taking its name from that technological epicenter between Kendall and Central Squares in which it resides, Area Four strives to be all things to all people. On paper, the idea of basing a restaurant around both a bakery/café and a bar/oven seemed intriguing, like a high bow, new-age Cheers for Cambridge denizens and the scientific intelligentsia.
