As someone who misses San Francisco every single day (Tony Bennett knew what he was talking about), let me chime in here: (1) There are lots of really cool spots to hang out in, and they are all really, really different. For example, if you want a sort of American Jackass-type bar crowd, Union St. is a great scene. This is where more "upscale" yuppies tend to hang out. If you want to meet a girl to go home with, I'd recommend this area. On the other hand, you could find some hipper places south of the park, some Irish-type dives on Geary toward in the avenues (there is a place on Geary and 6th, I think, that has amateur Irish bands that play quite a bit. It can get loud, but it's a good time). If you are looking for a late night wine and cheese bar, there is a little place in Union Square (downtown) called First Crush that I found quite enjoyable. Very small, but very friendly. The type of place that you might go with a really good friend late at night. I think they are open until 3 am or so, which is kind of rare downtown. Further south (Mission area) is a place called (I think) Julie's Supper Club -- I had a good time there once. You could also go down to Haight Ashbury -- not at all what it once was (or so I've been told), but there are some fun spots there (I had friends that used to go to Cha Cha Cha down there). In my opinion, if you are alone and want to meet friendly people, avoid Union St. and even the Mission area -- simply too "gentfrified" a crowd for my tastes. (2) Shopping -- I can't help you that much other than to say that you can't go wrong in Union Square and the mile radius around that area. Everything from the Levis flagship store to Wilkes Bashford. I didn't have much money when I was there, so I don't know any secret hotspots. (3) San Francisco is the greatest place on Earth, and you'll never know it from just one weekend . . . or even a month . . . or even a year. What makes San Francisco special is not the shopping (which is darn good), or the food (which is also terrific), or the weather (SF weather is remarkably underrated IMO), or the recreational opportunities (first class), or the culture (also first class), or the physical beauty (can't get any better) . . . it is the fact that after living there for an extended period of time, you'll forget you are in San Francisco entirely. You'll simply feel like you are "home." It has that effect, and I've only felt like that in one other place -- my actual "home" where I was born and raised. So, I guess what I am saying is that if you get the job, and you could see yourself being happy in the job, trust me that you will end up falling in love with San Francisco -- even if you aren't all that taken with it after just one weekend. Trust me.
