With a house full of children
, and another one on the way
, it makes sense that Tori Spelling
's hubby Dean McDermott knows a thing or two about cooking up a kids' meal.
The reality star put his chef skills to the test on Tuesday night when he cooked up a fancy child-friendly feast – but for none other than a group of about 15 adults – at the Andaz West Hollywood hotel. To celebrate the launch of his lifestyle concept website TheGourmetDad.com
, the proud papa worked up a five-course meal of his favorite recipes that appeal to adults, but also appear fun to eat for kids and contain proper nutrients.
"One of the meals was a piece of salmon that was made to look like a surfboard," an attendee at the dinner tells PEOPLE. "And there were blue mashed potatoes that were made to look like the ocean. It was really fun-themed."
Of the cooking duties, which were shared with the hotel's chef Jorge Chicas, the source says, "Dean worked away at it the entire dinner. He was decked out in full chef attire and seemed really into explaining the dishes and making sure the guests enjoyed his food."
At the end of the night, says the source, "Dean made these mini-Rice Crispy treats and talked about how they were a big hit at his daughter Stella's birthday party." – Dahvi Shira
