I did the North Beach tour with Natasha back in March. It was a really, really great tour. It was super informative and Natasha really knew her stuff, she answered all of our questions without any problems. It was really fun to walk around San Fran with a local; every two steps Natasha gave us another recommendation for food/coffee/fun/whatever! I found out things about the neighbourhood that I never would have known if I hadn't done the tour. Natasha was also kind enough to have a long chat as we walked down to the piers and give me an even bigger list of things to do! I have done Discover Walks in Paris as well, and would highly recommend that you do them no matter which city you're visiting!
