Billionaire businessman Nelson Peltz threw a lavish bar mitzvah for his twin sons on Saturday night, the cost of which guests estimated at $2 million, according to the New York Post‘s Page Six.

Held at the Pierre Hotel in New York City, the event — honoring Zachary and Gregory Peltz — featured stilt-walkers, a hockey rink, a basketball hoop, a video arcade, two bands and five singers, for the entertainment of the hundreds of attendees, among them Madison Square Garden executive chairman James Dolan.

Pointing to the many photographers and videographers at the event, Peltz, who co-founded the investment firm Trian Fund Management LP, quipped, “At my bar mitzvah, there were two pictures taken.”

The 73-year-old New York Jew has 10 children, including actress Nicola Peltz, actor Will Peltz and hockey player Brad Peltz. The senior Peltz has a net worth of 1.35 billion and his company is one of the fastest growing hedge funds, with more than $10 billion in assets, according to Forbes magazine. Page Six noted that Trian Fund Management, which recently eliminated its stake in PepsiCo Inc., is worth some $2 billion.

Peltz is also the co-chairman of the Simon Wiesenthal Center’s Board of Trustees.
