Westchester just got lucky. How often is it that a top-rated Manhattan restaurant opens an annex in the suburbs? Not often enough, we know. But Benjamin Steakhouse, the famous restaurant on 41st Street in New York City has opened its second location in White Plains. The dark wood dining room with banquette seating, burgundy booths and chocolate leather chairs includes a warm oversized fireplace. Sumptuous seafood offerings are also available. 601 West Hartsdale, Ave, White Plains. 428-6868. www.benjaminsteakhouse.com.
