DaGreenTeam/Splash NewsMark Zuckerberg may be a billionaire, but he apparently doesn't have to spend loads of cash to enjoy himself.
The man behind Facebook showed that he still appreciates the simple things in life by going on a Hawaiian vacation with doctor wife Priscilla Chan that, well, resembled a vacay that a non-billionaire might take.
Zuckerberg and his lady were spotted exploring the island of Kauai, just like any other pair of tourists, while in casual clothing and comfortable sandals.
The duo also opted for Kauai's famous Bubba hamburgers and smoothies rather than lavish meals.
A source tells E! News that the couple seemed very happy and relaxed while enjoying their getaway with a group of friends, adding, "They were very chill and down to earth!"
When they weren't chowing down on some burgers during their five-day stay in Hawaii, Zuckerberg and Chan hit the beach for surfing.
