Most restaurants, still depends on the WOM (Word Of Mouth) expecting the customers to spread the news about their dining experiences to family and friends. In our electronic age things fly faster and might hurt quicker and are more painful than ever. The WOM is more powerful than any press review through social media. An unhappy guest can leave a nasty review about your restaurant, wich will stay for years. A damaging review might cost the restaurant thousand of dollars income.
