A friend and I (both former Manhattan residents) attended this tour together and we thought it was fabulous. Our guide, John, was extremely knowledgeable and had a great sense of humor. Furthermore, he had an obvious love for the subject, which made his stories all the more fascinating. If you want to see the little nooks and crannies you'd never noticed and hear the historical tidbits that make them special, this is the tour for you. Highly recommend to both tourists and residents who want to see more of their own city.
