“First we eat, then we do everything else,” said M.F.K. Fisher, the food writer who serves as both the inspiration and namesake for this local darling. Thanks to large windows, whitewashed brick walls and silver-and-white tilework, the subterranean space manages to evoke a breezy oasis. Organized from small to large plates, the thoughtfully composed, Iberian-inspired menu follows suit.Daily specials are certainly worth ordering, including the clove-infused tender, shredded oxtail. Other simple, flavorful dishes, like warm boquerónes stuffed with marinated anchovies and Fresno chilies, or croquettes with Montamoré cheese and Sherry aïoli are equally tempting. A crumbly slice of Basque cake and an expertly pulled cortado end the meal on a high note.
