Disney in Anaheim is good if you are taking kids with you. Traffic gets bad around there so arrive early and pick a week day if you can.
Westfield Century City is a decent shopping mall if you need a few bits. Food court is okay. Depending on your direction of travel it is enroute to Hollywood. Universal Studios is a good attraction too.
This pizza place is a must if you like your pizza:
