Totally a locals hangout.
This very unpretentious wine bar is a favorite. The owner, Darlene, has a great selection of wines from smaller labels for you to try. If you're not sure what to get they'll help you find a bottle in your price range. They've got the cheap stuff all the way to the $80+ range (if you feel like spending some money).
You can buy a bottle at retail, open it up at their bar and enjoy it with a nosh. Lots of smaller appetizers (cheese and crackers, etc). Or, order by the glass/flight from their bar.
Checkout their website before you go. Or if you live in the area, subscribe to their email newsletter. There is something different going on every day (live music, tastings, specials, etc.)
