The 40/40 Club is a chain of sports bars and lounges owned by hip hop mogul Jay-Z and business partners. The name is borrowed from the baseball term  used to denote the exclusive group of Major League Baseball players who have achieved the rare individual feat of recording 40 home runs and 40 stolen bases in a single season.
On June 18, 2003, the first 40/40 Club opened in New York City at 6 West 25th Street just west of Broadway; the Atlantic City location opened on October 25, 2005. The third 40/40 Club was located in The Palazzo, an extension of The Venetian in Las Vegas; its grand opening was held December 30, 2007.
The venues are known for their live music, celebrity patrons, and sports memorabilia. The brand gained recognition when Jay-Z referenced his investment in his 2003 song "Dirt Off Your Shoulder" with the line "Now you chillin' with a boss, bitch of course SC on the sleeve / at the 40/40 club ESPN on the screen".
The decor of The 40/40 Club is a mix of memorabilia from the USA's greatest games. The “Hall of Fame” connects the main floor with the upstairs VIP rooms and houses autographed jerseys donated by various sports celebrities. The jerseys hang museum style, as well as decorate points of the lounges along with other sports memorabilia, such as the autographed gloves from the 1974 “Fight of the Century”: Ali vs. Frazier and the WWF championship belt of Kurt Angle.
