Australian restaurateur Benjamin Christie gives the following advice:
"Give Facebook users a reason to become a fan of your Facebook Restaurant Page.
Why not do a monthly dinner for two giveaway, exclusively for Facebook Fans. Or all Facebook Fans get a glass of sparkling wine on arrival.
Why all this to get people to become Fans? These people will be come ambassadors for your restaurant, every person will now have a link to your Facebook Restaurant Page on their page, kind of endorsing your restaurant in many ways. This in itself have a viral effect and will, over time help bring diners to the door."
