According to the Boston Business Journal, Legal Sea Foods will be opening a restaurant at 242 Northern Avenue in the Seaport District of Boston, the spot where Jimmy's Harborside resided since the early 20th century. The restaurant, which will apparently be an upscale complex, will be more than 20,000 square feet in size, and will include a roofdeck. The restaurant is slated to open in 2010.
