Pros of food trucks: mobile, modern look, guests see the food being prepared, less formal and often cheaper. Variety is added when you place several trucks side by side. Cons: weather-dependent, limited seating, queues, a limited number of menus and less elegant for gala dinners. Traditional catering is more elegant, but less playful. For informal corporate gatherings we choose food trucks. For a formal gala, traditional catering is the better fit.
