We joined the tour at an easy to find landmark near Times Square. For a non fan, it's an interesting trip out of the city to New Jersey, for the fan the trip is a series of stops walk abouts video clips with commentary by an actor from the series. Even if you have only been able to watch the first 4 episodes the scenes will be familiar and brought to life from emerging from the tunnel sitting eating onion rings or sipping a beer at the Bada Bing.
We travelled to NY as a group of 4 , with this tour as a gift for a big fan, but we all really enjoyed it and would recommend it - shopping can wait a while!
