RE: A little help, please
Al is right -- you need some pics of people in there! Doesn't matter if they don't plan to stay with you for a while. You're just trying to communicate an atmosphere; no one will notice or care if the faces are different when they eat at your place. That is, as long as you don't identify them by name or highlight their personalities. Just a few smiling staff faces would do the trick. Or, as someone else suggested, happy diners. BUt you definitely need the human element in there!
