Enclosed by light-pouring windows, this Williamsburg restaurant lives up to its name with fresh and airy entreés -- many of which are seafood-focused (tilefish chanterelles, grilled octopus), and many of which are not (dry-aged cheeseburger with manchego, beef carpaccio). While Lighthouse definitely delivers with its main dishes, a selection of shareable small plates featuring house-made sourdough, pickles, and cured meats, are impressive and substantial.
