Aurora Town Square offers a couple different ways for you to purchase a beverage or snack pre-show or during intermission.  There is a fully licensed bar outside of the Performance Hall that serves alcoholic and non-alcoholic drinks, as well as the Armoury Cafe* on the plaza level (facing Aurora Public Library), which also provides some light food options.

And yes, you will be able to bring your items into the Performance Hall during the show!

*Cafe Hours are currently Monday-Friday from 8:30am-7pm, Saturday from 8:30am-6pm and Sunday from 8:30am-4pm.
