I haven't been to Restaurant Week there, mostly because their regular prix fixe dinner is $35. I try to save my RW evenings for places I shouldn't really afford...Mistral, Aquitaine, Icarus.
That being said, you will have a good meal there. And they give you *four* courses.
I like their mussles and the roast chicken is very moist and flavorful.

as with bgavin, i find their normal prix fixe a bargain so don't go restaurant week. however, i'd be surprised if you didn't find good stuff here. I love the polenta with caponata if they have it, their rabbit and their chicken mattone. the only thing i haven't liked here is the profiteroles, but then I generally find them too heavy everywhere outside of France.
