I went here for the first time tonight. I should tell you that I am a long long time fan of The Lost Bean ( I was their Duchess for a while in fact) tonight, my friends and I decided to hit up The Lost Vine. Minus the staff, it was lovely. The selection of wine was tasty and reasonable priced, the ambiance is really nice but unfortunately I have to take away a few stars because  of the employee working the wine bar. She was so drunk, and told us that she was. First she didn't card any of us. Everyone at our table was over 21 but a few of us definitely look young. She was slamming our cups down on the table and telling us not to get too rowdy because the table was wobbly... unfortunately she was the one that was slamming our cups down and shaking the table. She opened our wine at the bar, away from our table, and then let it sit there for a good 5-10 minutes while she talked to her friend. At one point she tried tossing something to her friend and it went flying over the bar on to the floor by us. Rather than walking around the counter she climbed over the counter and was crawling on her knees for a while, once she made a few jokes about being on her knees, she hoped back up and over the table  again.  I love The Lost Bean and I had such high hopes for The Lost Vine but unfortunately I was quite let down tonight.

Went on a Friday night and there happened to be live music (usually only on Thursdays), and the Hicks Canyon Band was playing. I hadn't heard of them before but they were truly great!
I had a glass of garnacha that was delicious! I especially appreciated the sign that said the Lost Vine is for conversations - no computers/books after 5:00pm.
I definitely plan to come back every Thursday even though it's kind of far from me.
