Where in SF are you living that you feel threatened?! WOW! I loved that city.

Make sure to have a few Irish coffees at the Buena Vista Cafe, and be sure to partake of some of the traditional Chinese restaurants. I'm talking about places that offer things like hot and spicy tripe and Hog Maws with black beans. It's better overall than any other place in the US, I think.
Cheers!
