I'm taking my sweetie to a screening at the Castro Theatre on Valentine's Day and am looking at places close by for dinner afterward. Neither of us live in SF so I don't know the scene as well as I'd like, although this is not a first visit and I do have my favorite spots in the city. I'd like someplace fairly low-key but sweet, and I know VD brings out the worst in some places. L'Ardoise looks about right- any thoughts on that, or other suggestions? Thanks!
