The Carnegie Club was a Midtown hotel that became, for all intents and purposes, the Barzini family's social club, it was run by the mysterious Fernando Riviera, and contained a brothel on the upper floors run by Margo Le Mauvais.The Club was never attacked due to it being so close to the Barzini compound. The Barzinis went to the mattresses here during the Five Families War and continued to use this hotel as a base until it was taken over by the Corleones in 1954.
