Add Hoseki to the list of excellent alternative restaurants to be found along the Via Il Prato. It's a sleek, cozy dining room with attentive servers and a first-class sushi chef. This may be the first time I'd ever seen branzino included on the list of ingredients for a special roll, but the results were top-drawer. The fish is uniformly fresh and tender. The kitchen also tosses together a mean seaweed salad and piping-hot edamame. All around, it's an excellent break from traditional Tuscan fare, and a good deal more than respectable on its own merits.
