The house itself is accurate, but the neighborhood is nothing like the movie (2 doors down, the owner has converted his front yard into a parking lot, capitalizing on the limited on-street parking). Take a look at Google's street view.
I've been a fan of Jean Shepherd since listening to his radio shows in the 1970's, so I'm glad I made the visit, but for $12 a person, the tour isn't cheap (and let's face-it, it's nothing more than an old house).
