David is a great guide. He is funny and witty, and starts the tour by asking our names and the occasion that brought us here. And I am amazed he remembers everything! The tour really was in 2 parts. The first was Chelsey Market, where we tried dumplings, pizza, hot sauce, Japanese tacos, mini donuts , and vegan ice cream. David was really knowledgeable about the history of Chelsey market which added to the experience. The second part was the High line walk, where he talked about architecture of the buildings among other things. It was not a grueling walk by any means, but I would suggest you might bring a bottle of water with you to stay hydrated, especially in warmer weather.
This was an unexpected favorite part of our trip to NYC, and is well worth it to book this tour, especially if you get David as your tour guide .
