Inside the theatre
Usually in the area on the bottom floor adjacent to the food court. As others have noted, you can buy them on-line, as well. Or save your money until the movie is on Netflix or Amazon.
You need to buy them online at least a few hours in advance to get a seat for newer movies. The theater has been reconfigured and there are fewer seats so buying in advance is important. If the movie has been out for a while, you can get tickets online or at the kiosks in the theater lobby across from the concessions stand. Thus is also where you pick up your online tickets. Some times when it's busy the card readers get jammed up and you have to go to the concierge desk to get tickets.
You can buy them online, at the kiosk on the far end of the food court, or at the self service kiosks on the second floor near the concessions. I normally buy them online or at the self service kiosks
