Chuck E. Cheese, the U.S. restaurant chain that emerged from bankruptcy three years ago, is exploring a sale amid acquisition interest. The company, known for its arcade games and rat mascot “Chuck E.” Cheese, is working with investment bank Goldman Sachs on an auction process that could attract private equity firms as well as peers such as Dave & Busters Entertainment. Private equity firm Apollo Global Management Inc acquired Chuck E. Cheese in 2014 for $1.3 billion, including debt.
