Yes, it s actually in Universal Studios. The only way you can see it is when they drive by it on the Backlot Tour.
i visit it in a guided tour in universal studios but you must know that the houses is not real !!! it is only a large front made of wood,,,!!!!not real house ,,but when we was in the bus they make the music of despret houswife while circling in the street ,it was a strange nice feeling of being in the street
As far as I know there is a tour bus that takes you round all these places including Wysteria Lane. My girlfriend went to LA this year and went on the tour, the pictures looked awesome!!You might find this link interesting:http://www.thestudiotour.com/ush/backlot��
