I tried booking a while ago but unfortunately there were no more adventurous people that wanted to join the tour that night. So I took the leap and splurged for a private tour. It was the best money I spent in my 5 days in HK!!!! Michael is super friendly and most important knowledgeable. He did not tire from all my questions and you can easily tell he has the know and the passion. I highly recommend this particular tour because if you are interested in the local culture, and food is the way to go about it, you need Micael to guide you. I hope to return one day!
