There is also one near the Disney Outlet store, I went to that one after going to the Outlet store. I will say I am very happy that they are not on the East Coast or I would be there everyday, they are delicious.
It's at the Orangefair Mall, which is north on Harbor Blvd about 3-4 miles, on the southeast corner of Orangethorpe. The In-N-Out Burger in that vicinity is just north of Orangethorpe on Harbor. Other good eats in the area include Ruby's Diner (s/w corner of Harbor and Orangethorpe) and Spaghetti Factory at the Fullerton Amtrak station further north on Harbor a mile or so.
I was there about a month ago and got some good deals. A fleece for 19.99 for example. They had a lot of kids costumes. I also had a 10% from the Orange County Website.
