Numerous studies show people love with eyes. They would rather pick tasty & colorful food or drink that they see in a picture that probably even more delicious thing that is grayer and paler, even if it is on their plate right now.

 A lot of factors contribute to it, though: like hunger, the desire of something specific that they see in some particularly beautiful picture, if they are eating right now and if yes, how tasty it is. 

In other words, with the right food videography, you can make your clients salivate thinking about how they would eat a tasty piece of what is advertised. If your food promo will be shown on a TV and a person sees it, he or she may eat it if that is available in the fridge. If not, they would think about visiting your restaurant, cafe, or bar. 

Think, how often did you catch yourself on a thought that you would eat this tasty Big Mac right now? Or a dish of pasta with cheese and shrimps (that you happen to see on a TV or a big board)? That is exactly how restaurant promo video works and every food industry specialist completely understands that a savory visual picture attracts new customers more than anything.
