1) Wolffer's vineyards are always gorgeous in the summer, but give them a little sunset backdrop and bamn! instant romantic photo-up.
2) There's live jazz; and jazz always gets better with wine
3) The wines, or at least most of them, are really good, I think (I don't really know wine. at all).
4) There's free cheese.
5) Actually, the whole shebang is free AND there's no reservations necessary. See you there!
