The drive up to this place is lovely with views of the coast most of the way up the mountain. Nearing the top, the vegetation gives way to mostly rock and sand and you can start to appreciate the 'desert' part of LA.
I went here with some friends of mine and arrived just before 4pm. We packed our own dinner and ordered the holiday flight of wine. I'm not a wine person so I can't comment on the wine but the atmosphere of this place was like crashing someone's outdoor ranch-style wedding - in a great way. The band was playing hits from the 70s and 80s, lots of people were dancing, lots of little white lights which gave the place a nice glow for light and there was a really awesome happy vibe to everyone in the place but this might have also had to do with arriving within 2 hours of closing!
We visited the place on a Sunday night. If I had to do it over again, I would still stay around 2hrs but plan to arrive an hour earlier so we could enjoy the place with the band playing in the background.
A nod to the good service at the bar, they were casual or chatty depending on your own vibe and they kept track of your tasting so you could enjoy each glass at whatever pace suited you. It probably goes without saying that you can bring your own food but you can't bring any alcohol with you to this place.
There is valet parking but you can keep the 14$ for drinking by driving 5 mins further down the road to their larger parking lot and using their free shuttle (looks like an old trolley car complete with wooden bench seating). There was no schedule to the shuttle but we only ended up waiting at the end of the night (about 5mins) for a pickup.
