It might be time for Alberto Del Bello to spruce up the most swank of his three establishments. A well-trod carpet and slightly dull chandeliers shouldn’t distract from the tall, lemony arugula salad with fresh artichokes and shaved parmesan; the soft twin polenta cakes with earthy portobellos; the snappy house-made tagliolini with wild boar; or the spicy seafood risotto, with its sprawl of perfectly cooked langoustines, calamari, mussels, shrimp, tuna, salmon and other fish across a wide white plate.
