What's A Food Park?

Moments ago, the Fort Worth Food Park, that haven for food-truck foodies, announced on its Facebook page that it will open Dec. 2. The park will be at 2509 Weisenberger St., a couple of blocks south of White Settlement Road and just north of the Seventh Street Target.
Charter trucks include Good Karma Kitchen, YES! Taco, Nammi Truck, Lee's Grilled Cheese, cupcake-mobile Red Jett Sweets,and a Jake's Hamburgers truck.
Rest of article here. And I still don't understand the concept.
