Saha on Sutter
Saha is my current favorite restaurant. I love their food.
After years of refusing to go out on Valentine's Day, last yeat we went to Saha. It was everything people complain about on VDay - crowded, staff had difficulty keeping up with service, luxury foods at a premium prices - that said, it was probably the best possible experience one can have on VDay.
But Saha's food is so good and so reasonably priced normally, that I would say that if your first visit is on VDay, you won't be meeting them at their best.
Anyway, this year, we're staying home.
