Repeal of Prohibition (1933)
The 21st Amendment ended the 18th Amendment's national alcohol ban and handed states control over alcohol sales. States built tiered license systems, many tying a bar's right to serve to food service as a public-safety measure.
States issued a wave of licenses as the modern three-tier distribution system took shape.
California's license categories today, including the type 47 eating-place license Mars Bar holds, descend from that post-Prohibition framework.
Explains why Mars Bar's license requires food service alongside alcohol rather than allowing a bar-only operation.
