Best wine bars in SF

So, in SF only, what are some of the best wine bars you've been at lately. I'm looking in terms of selection, price and food.

I've been to Nectar, but they don't really serve food there. Bin 38 in the Marina is very cool, prices are reasonable and they have good food. First Crush is good, but more like a place for a date, and not to go wine tasting with friends and hang out. Bacar is overpriced and overrated. Ottimista Enoteca'cafe is good and I like the fact that they offer different types and styles of wine, but it's often crowded on the weekends and hard to get a seat. Cellar 360 in Ghiradelli is good, but a little pricey. It's more like going to Napa, you stand at the bar. K&L Wine merchants has wine tasting on Saturdays and for $20, you get to taste a lot. So what are your favorites? I want to go visit more and make up a Top 10 list.
