BROOKLYN, N.Y. - Catering a wedding used to be province of restaurants and specialized catering firms, but a new kid in town is honing in on their business as the humble food truck capitalizes on its flexibility and creativity, the Wall Street Journal reports.

Amy Maureen Yee hired three food trucks to cater her May wedding. "We started to look at traditional caterers and the costs were just crazy," she said. The trucks cost a third of the catered price.

Food trucks are being hired to serve bar mitzvahs, corporate clients, TV film crews and weddings. Some even advertise non-competing products, such as Coach bags, airlines or corporate food chains. "We have a major company that is looking to us to promote their brand," said Grant Di Mille, president and co-founder of Sweetery, a three-truck operation. "How interesting is that? That a company with 250-plus retail locations, a multimillion-dollar company, is coming to us to promote their brand."

The explosion of food trucks and their ability to adapt to different circumstances has made these moveable feasts very successful. "Weddings have been really good for us," said David Weber, who co-owns the Rickshaw Dumpling Truck. "Bat mitzvahs are also really popular."

David Belanich, whose Joyride sells coffee and frozen yogurt, says around 20 percent of his profit is from catering and corporate events.
