Just a straight shot north on Harbor, about 9 miles from Disneyland, on the northeast corner of Harbor and La Habra. You can't miss it, there's a big yellow sign, which if you're coming in from towards Disneyland, will be on your right. Since I moved to Stockton from La Habra back in January 2000, I've eaten there at least once every single trip I took back down south. In fact, when I go down south, my 2 constants are Disneyland and Arthur's. When they say "best breakfast in town", they mean it. Whenever I eat there, I usually order #9 (country fried steak and eggs), over medium, plain potatoes (as opposed to O'Brien potatoes) well done, and biscuits with a side of gravy. They have the best biscuits and gravy in California. I also like to have a glass of fresh squeezed orange juice (and I do mean fresh squeezed, the juice I drink on Sunday tastes like the oranges were still on the tree on Saturday).
