Gavin Rossdale & Son Love Lunch Dates Together

Lunch with Kingston Rossdale is one of his musician dad's favorite weekly gigs.

"I have so much fun taking Kingston out for lunch; it is something I look forward to on a regular basis," Gavin Rossdale tells PEOPLE about his 2-year-old son with wife Gwen Stefani. "He really loves noodles. I think that has become his favorite food. We try to find new places to order them."

Rossdale, 40, says that he takes Kingston out alone so mom can take care of their 3-month-old son, Zuma.

"Gwen is amazing with Zuma and does most everything while I just hang out," he admits. "Even though we share responsibilities with the kids, Gwen definitely does more than I do."

Rossdale, an accomplished tennis player, spoke with PEOPLE Saturday night during the 19th annual Chris Evert/Raymond James Pro-Celebrity Tennis Classic in Delray Beach, Fla., where he and tennis star Justin Gimelstob beat Jim Courier and Jon Lovitz in the first day's match.

So why don't Gwen and the kids come watch Daddy play tennis with other stars like 12-time Olympic medalist Dara Torres, and comedians Billy Crystal and Chevy Chase?

"Gwen never comes because she doesn't do what I do," says Rossdale, all decked out in a handsome black tux. "She doesn't play tennis or get ready for events quickly!"
