Did they have bars in 1930?

Yes. Bars, or establishments that primarily serve alcoholic drinks, have existed for centuries, including during the 1930s. Despite the challenges posed by the prohibition era in the United States, bars continued to operate clandestinely in various forms during the 1930s when alcohol production, sale, and transportation were illegal under federal law. These venues were called speakeasies and played an integral part in the underground alcohol trade. After the prohibition ended in 1933, bars could operate openly again, and new establishments began to emerge alongside pre-existing ones.
