I noticed that Sherri J mentioned the setup looked like it was from the 70s and she's correct. I saw photos of my parents sitting in a booth there in 1979 and the furniture and decor was identical to what it is now.
The restaurant was originally called just Earl's. I think they added the "Crazy" to it in recent years to hopefully drum up business. The food quality has gone steadily down hill the past 8 years. I used to come here as kid when I visited my grandparents in Sun City. It its heyday you'd have to wait for an hour for a table. The good was delicious especially the Mexican pizza. It was the best Mexican pizza I've ever had anywhere.
The original location was down the street and around the corner in the northeast corner of the strip mall on 99th Ave and Peoria. In the early 2000s it moved to the current spot and immediately the meat used in all the dishes got horrible, like they started using low quality institutional stuff to save money. The Mexican pizza, which uses ground beef, remained the same so I guess it was cheap enough not to substitute with junk meat. But we noticed as the years passed the parking lot got less and less full as did the dining room.
We used to drive 40 miles to come here up until a few years ago. It was worth it if we just intended to have the Mexican pizza which used to be only $4.99 for a 12 inch then went up to close to $8 but was so delicious it didn't matter. After a while not everyone wanted just the pizza and everything else on the menu was so god-awful we just stopped coming.
