Have any of you noticed that a number of restaurant review sites have become a voice for disgruntled customers and don't really give a fair overall picture of the food and service? I made reservations for a Los Angeles restaurant on Valentine's day, and only checked the reviews later (Yelp and Urban Spoon). I was so discouraged with what I read that I almost canceled the reservation. But I decided to go anyway (because they had monkfish on the menu!) and I was delighted by my experience. Now I am beginning to wonder if more people are motivated to write a review when they are unhappy with the food or service as a form of revenge, and the guests who are satisfied don't write anything-- making the reviews very negatively skewed. Have any of you noticed this? How do you size up a restaurant when they have some very negative reviews? Do you avoid such restaurants or take a calculated risk on them?
