After seeing Attack of the Clones several times, I then saw it at the Cinerama. I couldn't believe the difference! The picture, the sound, everything.. I never want to see a movie anywhere else if I can help it. On top of all that, they have very comfortable seats and a nicely decorated theater to boot.
Pros: Huge screen, Amazing Sound, Comfy seats
Cons: Difficult to park, Shames other theaters
