The EMP is an awesome architectural piece and you can experience that bit for free! Once you go inside, though, it has more cool stuff to show you. It has a nice cafe (although the prices are quite steep) and some really great exhibits. When I went the Nirvana exhibit was there (which I don't think is permanent) and it was one of the coolest exhibits I've ever experienced. Without this exhibit the price of admission is still worth it for the Science Fiction and Horror section and possibly whatever other traveling exhibits show up.
