Well, technically, if they aren’t wearing swimsuits, and their basketball shorts aren’t dirty or torn (I’m not sure what your objection to boobs is…many evening gowns that would meet any dress code show some boob) they ARE doing the bare minimum to comply with the Cali Grill Dress Code, which states:
This restaurant is a Disney Signature Dining experience offering fine dining with a distinctly magical flair. Guests are expected to dress accordingly in attire that respects the restaurant's sophisticated and upscale aesthetic. Clothing should be clean, neat and in good condition. Please no swimwear.
