A number of other retail mainstays dot Long Island. Century 21 Department stores established a location in Westbury several years ago. Century 21 has been a popular store in Downtown Manhattan and Brooklyn for some time. Fortunoff, an upscale department store, has its main store in Westbury, a Backyard Store at the Smithaven Mall in Lake Grove, and a clearance center in Garden City.
