The Korova Milk Bar was featured in the book 'A Clockwork Orange' by Anthony Burgess and more famously the film adaptation by Stanley Kubrick of the same title. The Korova Milk Bar is a bar for minors that sells "Milk Plus" meaning the milk is often laced with a drug of your choice, either Vellocet, Synthemesc, Drencrom. Vellocet in the story is supposed to be a fictional opioid, probably similar to the ultra rare and coveted opioid dextromoramide said to be the most euphoric opioid ever when taken by mouth. Synthemesc is based of mescaline but a synthetic variant with similar effects presumably. Lastly Drencrom is Adrenochrome a real substance derived from epinephrine with strong euphoric stimulant effects similar to amphetamines and other unknown effects at higher doses. The bar features furniture in the shape of naked women and milk dispenses out of the nipples. Korova means "cow" in Russian.
