I was visiting the area while ago and gave this place a try, which turned out to be a great choice. i took the 'gangsters murderers and weirdos' tour at the East Village Visitors Center, and not only do they tell you about the obvious- history, which is of course very important- but also some sutff even the locals don't know about. East Village Visitors Center is definitely a must-go spot for anyone visiting the city.
I came here recently after a friend from out of town recommended a tour he had taken. I went on the gangsters, murderers and weirdos tour and found it fascinating to learn about things that had happened at places that I walk by all the time! The tour guide was cool and knew so much about the history of the east village. this is the kind of thing that even people who've lived in new york their whole lives could do and still learn from. also the cafe it operates out of has really yummy coffee for only a dollar!
