Our tour guide, Jeff, was extremely knowledgeable and enthusiastic about the subject. He explained all kinds of details to us and kept everything interesting. I learned a lot from him. He pointed out the pink marble which I would never have even noticed, the garlands, tulips and poppies on the wall, etc. His explanation of the history of how the subway got started, the stories about the people involved, the extra laminated pictures he brought, everything about the tour was great. It was well worth taking and I would recommend taking any tour led by him if one is interested in New York City history.
