Ok, I've narrowed it down to these two spots picked purely from reviews etc. We're only spending a night in SF before we head up towards Napa.
One's French and the other American (I think). Has anyone been to either or both? Not sure which one we should be trying, though we should be trying "Californian" cuisine since we're there, so I'm leaning more towards Blue Plate.
We're looking for great food and a nice ambience, doesn't have to be romantic or anything, since we'll be doing all that stuff up in Napa ;)
