What is the best type of lighting for restaurant dining rooms?

This restaurant has no windows and lighting is an issue. We want a comfortable atmosphere with lighting that helps relieve the cave-like feeling the restaurant has with no windows. This is a high quality restaurant, so dim lighting is usually wanted, but we don’t want the lighting to be too dim. any suggestions?

Your best option is to get light switches with adjustable brightness. Older customers might prefer a little brighter light so they can read the menus, while the younger customers might want dimmer lights to set a more romantic mood. In either case, I’d say you can’t stick with one brightness setting, and must adjust as needed or if a customer makes a request.
