MILWAUKEE — While he’s more known for his five Dogg Haus restaurants around the city, Mazen Muna also owns Metro Hand Car Wash & Detailing, and considers that business his true love, according to OnMilwaukee.com.

"Cars have been my hobby since I was a little boy," said Muna. "I have … personally bought and sold over 50 cars in my lifetime thus far." Metro Hand is a high-end detailing shop, but the article states that Muna also prides himself on it being a place where anyone can come.

In a Mercedes S Class, you have about six in the doors and underneath the seats that are actually hiding places," says Muna.

While Muna is busy running his restaurants, the detailing business, which he works at on Saturdays, is a way for him to relax and show his employees how much he cares about the industry. "It creates a good work ethic when the owner is not lazy, and the owner is just not an it or a check. This is therapeutic for me."
