This is the sixth iteration of Mark Barak’s Italian restaurant, and, like the others, some of its features nod to the neighborhood. In the space that housed the popular Isabella’s — noted for its brunch-hungry crowds and densely packed sidewalk tables — Mr. Barak has installed a dining room, bar and lounge with warmer wood accents than in some of his other locations.

Of particular note are sweet wall sketches by Kimmy Quillin of Brooklyn, showing the signature white sheep of the restaurant’s name strolling around the Dakota, gamboling on the Sheep Meadow, boarding the subway at West 72nd Street and enjoying other Upper West Side landmarks.
