There is a Harkins movie theatre on Mill Avenue, along with many popular bars for the college crowd. It's a fun place to hang out, you can just walk to plenty of bars if you get bored. If you are going to be there for a while, you might wanna try:
The Library
RA
Owl's Nest
Hooters
Fat Tuesdays
Most of the bars on Mill always have decent 'scenery', although, on a Monday night on a holiday won't be as good as a weekend
Axis / Radius is in Old Town Scottsdale and is definitely the "cool" place to hang out, along with "Mist" which is right around the corner. If you are going to hit up these places, dress nice and bring your wallet. There's plenty of places to go in Scottsdale like Maloney's and Drift that don't require dressing up and buying 9 dollar shots, but still give you the girls to look at.
Good luck and have fun while you're here.
