"The Cotton Club was a club at 500 Jackson St. in the West Side of Las Vegas, Nevada, which was an exclusive club for African Americans. Established in late 1944 as a small bar by Moe Taub... In 1969, [Sarann] Preddy put in a club with Margie Elliot called the Playhouse Lounge at the location. They were unable to obtain a gaming license and after a year, sold the business. It reopened from 1970 to 1985 as "Love's Cocktail Lounge"..." https://en.wikipedia.org/wiki/Cotton_Club_(Las_Vegas)
