Lighting is one of the most important aspects of restaurants.

It has an incredible impact on the entire experience, mood and atmosphere.

Unfortunately many restaurants massively under-estimate its importance. 

Remember that the lighting should be all about the customers, and their experience. It should have nothing to do with the owners of the restaurant or the waiters.

Good restaurant lighting can significantly increase sales - and conversely bad lighting will reduce it and drive customers away.

The other thing is that lighting can make it conducive to eating more and drinking more alcohol, both of which can put a good bonus to the bill.

Avoid lighting that is functional in nature, as that will conflict with the mood.

Restaurant lighting must be only about mood. 

The only functional lights in a restaurant should be the emergency exit lights - every other light should be soft, dim and conducive to a great experience.

Low, dim lighting will heighten the entire experience. It will make the meal comfortable, intimate and relaxed. The word here is INTIMACY. 

Bright lights should only be used for fast food restaurants where you want customers in and out quickly.
