Butter is a Portovert Pick; the restaurant features French-American fare featuring organic, seasonal ingredients.Highlights include the Birch Room, an 80-seat venue covered with floor to ceiling birch branches. The main room, which seats 110, is picture perfect for modern treehuggers with a 20-foot high ceiling and a window to another world -- an oversized illuminated photograph at the rear of the restaurant gives the illusion that you're in a birch forest, not in downtown New York.
