Paradise Bakery is my favorite stop in the food court. They have great sandwiches and salads, even better than their food items are their cookies. I LOVE their cookies. My favorites alternate between the black and white chippers and the coconut chocolate chip cookie. There are two paradise locations in Orange County, one in Santa Ana and the other in Mission Viejo (check the website for details).
Just in case you are not close to a paradise bakery, you can have the whole cookie experience at home thanks to Picky Palate. I made a batch of the Chewy White Chocolate, Chocolate Cookie for my family and we loved them. They are exactly like their black and white chippers, except I made them bigger. Enjoy!
