City Center Bag Policy?

Has anyone had experience taking a backpack to City Center?

I'm seeing THE GOLDEN APPLE tomorrow and will be coming directly from traveling on a bus, so I will have my backpack with me. I assume they will look through it, but am I allowed to stow it under my seat, do I need to check it to a coat room (is there such a service available?) or will I be permitted to take it in at all?

I've emailed them but any quick answer would be greatly appreciated!

They'll look inside before you are allowed into the building - but my guess is as long as it's not deemed too big (i.e. it might block the aisle or row somehow) - I wouldn't expect any problems.
