The studio tour of NBC is fun and educational. You can see the sets where many of the daytime talk shows are taped. You can also see some of the history of the network here- from historic artifacts to interesting stories. The studio tour is cheap enough- about $10/person. My favorite thing about here though is the chance you can have to see a taping- I sent away for tickets to Conan O'brien's late night show and went with a couple of my friends to see this for free. It was definitely a fun experience- and stand by tickets for current tapings are available the days of most shows. Fun!
