Billionaire hedge fund manager Ken Griffin loves McDonald's
"It drives people nuts that I take them to McDonald's all the time," Griffin said in an interview with The Wall Street Journal's Rob Copeland.
"People have these images of what the successful business person is supposed to act like and be like and so forth," he said.
But everyone around Griffin knows that when he suggests going for a walk, what he really means is a trip to the fast-food restaurant.
Griffin's firm has mounted a strong comeback since its post-crisis lows.
Citadel is now more aggressive than ever, with assets under management soaring to $26 billion, according to the Journal.
Meanwhile, Griffin is going through a nasty divorce from his wife, Anne Dias-Griffin, who is also a money manager.
He filed for divorce while she was on vacation with their children in 2o14.
According to divorce filings, Griffin makes about $100 million a month ($68.5 million after taxes) - or $2.2 million a day.
That is a lot of Big Macs.
