This place is great. It can get busy and their parking lot gets full quickly, so watch out for that since it's on the ASU campus. Their menu has lots of options and they're good about substituting which is cool. Everything I've ordered I've enjoyed, and there's still more to try since I've never gotten anything on their breakfast menu. The employees are always nice and they're efficient at getting orders out in a timely manner.
I haven't been to their Old Town location since this is the one that's more central to my east valley friends, but I'd like to try it since it's closer to my house. All in all, the OCC has healthy, delicious dishes and drinks and it's a good option for people with any diet.
