Concession stands located on all three levels

At concession stand, or if in Lux, they bring it to you.

you buy it before or during the movie

Consetion stands?

Unless your in the Lux, you need to go to the counter, order and bring to your seat. If you're in the Lux, you can push a button and a server comes out, takes your order and brings it back
