Planet Hollywood Observatory

Niagara Falls, Canada

Originally founded by Demi Moore, Arnold Schwarzenegger, Sylvester Stallone, and Bruce Willis, the Planet Hollywood chain has never been as successful as they hoped, but it's still a great place to gawk at celebrity paraphernalia and enjoy a good meal at the same time. This giant spherical structure sits between the Town Center and the West Side, and it's usually pretty busy. Just like at a Hard Rock Cafe, part of the appeal is buying a T-shirt identifying the location you visited; if you don't want to brave the crowds at the restaurant, you can check out their standalone store just down the street on the West Side.
