The Grilled Chicken Caesar Salad and the Raspberry Avocado Salad are two of my favorite things to get here. The Raspberry Avocado is a good choice if you're looking for a lighter lunch, but passing up on their grilled chicken is hard for me to do. They have easily the best grilled chicken I've ever had from a place that uses a customizable restaurant format (similar to Chipotle's ordering format).
If you go to the downtown location though, I recommend ordering online from about 11:30-1:30 because it gets slammed with ASU students and workers on lunch break.
