Maremma or A Voce ?
Second the vote for A Voce. It outclasses Maremma in food, ambience and service; but you get what you pay for. A meal at A Voce is probably 50% more expensive than Maremma, and these price levels are reflective of the qualities of both restaurants. Have had good experiences at Maremma too, so go there if you're in the mood for something more laid back.
