AJ was our guide-funny, knowledgeble, hospitable, inclusive to the group and very genuine. We learned a lot and really enjoyed the experience, even though we are locals and knew some of the history she was talking about. The Chinatown part of the trip could have been more informative as we only experienced two of the alleys. There is a lot more to the authentic Chinatown that would have been interesting to everyone. A stop in Molinares and/or local North Beach cafe would have been fun and preferable to the Chinatown Dim Sum.
