I'm purchasing a gift certificate as an engagement present for a couple who is moving to San Francisco from NYC. I want to send them somewhere excellent, innovative, and modern to celebrate a special occasion. They are both 30, but are professionals, so somewhere not too stuffy but still classy. Price point: dinner between $150 and $300 for a couple. I can only compare to places in NYC, but something along the lines of ABC Kitchen, Marea, Daniel, Blue Hill, Annisa.
