The folks over at Happy Cow created this nifty directory of vegetarian, vegan and/or veg-friendly places to eat. You just plug in your location, set your parameters and click on go! Being a vegetarian I find it hard sometimes to find good restaurants with good vegi options and this is a great tool. And, yes, despite what you think about SF, it is difficult to find nice restaurants that have options for vegetarians and, especially, vegans.
So thank you Happy Cow!
