If you wish to go see a movie downtown in an awesome setting, then go to Pioneer Place. This is a shopping mall with over 80 different shops. It is like a huge atrium capped with a great big round dome at its apex. Light fills the area beneath the dome.
Ride the escalators all the way to the top...
Nice theater but I have never been searched for bring outside food to theater. I would understand if I had a big bag or backpack but I only had a wallet and I was still searched. Everyone was. Doesn't matter if you bought concession food you will be searched.
