Hi, I'm a NY chowhound coming to SF for the weekend for a wedding and am looking to find a wine store that stocks lots of CA wines and wines from abroad - esp. Italy - at inexpensive prices (if it specializes in hard to find wines it won't work for me, because I'm trying to find relatively inexpensive ($30 or less) wines for my wedding in Jamaica and the selection there is not the best). Any particular place in San Francisco you can recommend? (I don't have a car and no time to travel anywhere outside of the city). Also, it has to be open on Saturdays - since I only have a few hours before the wedding to shop. thanks in advance!
