Nate was extremely personable and very knowledgeable. I learned much more than expected about the history of gangs in New York and where the bodies are buried (so to speak). If you want to know about Five Points, Little Italy, and Chinatown gangs, this is definitely the tour for you.
The "ghosts" parts of the tour was equally fascinating, focusing mostly on large-scale deaths, which I won't spoil for anyone.
I do highly recommend the tour and will definitely take family on it if they come back into town to visit.
The only drawback was not much information on Irish gangs, hence the four instead of five stars.
