I will be visiting San Francisco in a couple of weeks. Any suggestions for things to do/see?

You can try the Exploratorium- SF's weirdest science museum. Or how about taking a boat cruise out to Alcatraz and Angel Island? There is also the Embarcadero, with Union Square and the Ghiradelli Chocolate factory. Ghiradelli gives tours, and there are some great shops and resteraunts in that area. Chinatown is another possibility, since you didn't go last time. If you want to do this, you can also go and see Lombard Street- the world's most crooked street. Market Street is where the cable cars run, and it's also where a lot of good shopping can be found. I could go on and on- San Francisco is one of my favorite cities.
