It looks like some of the additional options on the "Food Menu Item" are not working correctly, I was trying to set an additional class on the element, but even though the field is saved in the visual composer backend, that class name is not applied to the element anywhere in the chain. I would have thought that the class would be applied to the main div at the same level as "nectar_food_menu_item" but I don't see the class applied anywhere within that element or any of the child elements.
