I can only kick myself from all the way across the country. From all the dozens of visits I've had to burger heaven, I never ever thought to add cheese and grilled onions on some double dipped fries. Since I'm not into the secret sauce, I've always avoided the "Animal"option always going simple when ordering. Strictly "American" Style- ketchup & mustard only, with mustard toasting of the bun on the grill, cheese, and double lettuce for the extra roughage, and a Neapolitan Shake- choco, 'nilla, & strawberry to complete the hot mess.. Kudos to PZA for the fry kit invention.
