My husband and I booked a walking tour with Linda of All About Chinatown tours. Not only was she organized, prompt and very knowledgeable but she had such a fun personality. We were visiting San Francisco on a cruise for two days and were not happy with the options offered by the cruise line for shore excursions. We didn't take the lunch portion but we did take her advice on where to shop after the tour. We have been to San Francisco several times but never had toured Chinatown with someone that had lived there and it really was very interesting to hear about the history, how people live etc. You won't be disappointed with choosing this tour.
