Is it legal to have alcohol in California full nude strip clubs?

No, it is a federal law that alcohol is not permitted to be served in full nude strip clubs. Some areas uphold this rule more strictly than others. The law may sometimes be enforced to the extent that drinking is not permitted at the stage and other times alcohol may not be served within view of the nudity. There are a few establishments that exist and operate under an exception to the rule but they are few and far between.
