We went to Fava last night. It was very noisy (small room with tight seating and low ceiling) but food quality was high.
We had the lobster corn bisque, which was rich and very lobstery, as well as unusual in that the corn pieces were raw, lending a nice crispness and sweetness. The fried oysters and their accompanying sauce were pretty good, but I thought the garnish of sweet slaw and onions was better than the oysters themselves (incidentally, one of our fried oysters contained a good sized but lopsided pearl -- that was an interesting surprise).
The entree selection is diverse. There were at least four tempting fish entrees, and one each of chicken, lamb, pork, and beef. We went with a braised lamb shank with roasted garlic, brussel sprouts and mascarpone polenta and an extraordinarily thick "rack of pork" (a double pork chop), brined and roasted with a molasses glaze, whipped potatoes, roasted peach and apple chutney. The lamb was wonderfully fall-off-the-bone tender and flavorful. The pork was just a bit too salty from the brine but still rather good.
Wines were on the expensive side (ranging from $6-9/glass). Service was attentive but not overly formal. The total tab, including two apps, two entrees, and one glass of wine was $75 (including tax, before tip).
Overall, it was a good experience, and it was nice to find a restaurant of this quality in the suburbs. Parking is plentiful in the Needham Center commuter rail lot, right where the restaurant is located (in an old rail station building).
