We thoroughly enjoyed the underground tour. It was both informative and entertaining. We learned about the establishments that existed beneath street level (tavern and gambling hall that continued to do business during prohibition, living quarters for Chinese workers, meat-cutting room for the butcher, etc.), but we also visited and learned about one of the brothels that continued to do business into the latter part of the 20th century. Our tour guide did a wonderful job responding to questions, as well as delivering the historical content in a lighthearted, comedic manner. Highly recommended!
