Hi gang. I need some current dining recommendations in SFO please. They need to be in the Union Square area, suitable for business lunches or dinners with existing and potential clients. I would personally prefer to go outside of Union Square but that's where the (very packed) conference is and we won't have time to wander afar.

I assume the major hotels (St. Francis, Hilton, Westin, FS etc) are all adequate. Anywhere else?

Thanks!
