There's a bustling, enticing rhythm here as platters of glistening shellfish get whisked from the oyster bar to the bright dining room. The menu is seasonally driven; all the seafood greats are represented. Start with steamed mussels, the Fijian albacore tuna Niçoise salad, or a New England–style lobster roll. For entrées, consider the line-caught Baja mahimahi sautéed with a pomegranate glaze, the Atlantic cod fish-and-chips, and the bigeye tuna rubbed with maitake mushrooms. Excellent desserts and a fine wine list round out this top-notch (albeit pricey) downtown dining experience.
