Went to SFO VS lounge in November. It was great and virtually completely empty in the 11am-noon hour. The offerings, in my opinion, are even a cut above AA's FD, QF's F LAX dining, or even CX Pier F dining with a diversity of tasty foods (AA cannot for its life do anything right in any Asian dish) and excellent cocktail menu. I would say that this may be the best lounge at SFO right now.
