Restaurants thrive not only because of the innate instinct of humans to be hungry and seek nourishment but other factors are involved. Success or failure of any gourmet restaurants depends on the quality of food and services they offer.
Ambience and location are also equally important. Before the invention of mass media, restaurants are advertised by word-of-mouth. However, today the popularity of a restaurant may not only be dependent on the skills of the chef. Magazine and newspaper
reviews by food critics also play vital roles. Reviews are free forms of advertisements that are like double-edged swords which may work either ways, for good or bad.
