Tim Zagat is an American publisher. With his wife Nina, he co-publishes ZagatSurvey, the best-selling restaurant guide in New York. Known to everyone as Zagat’s, the idea behind the guide is simple. Rather than reproduce the opinions of professional food critics, Zagat’s is a distilation of over 16,000 different people’s opinions, each having filled out a questionnaire. The result is a survey of 1,800 New York restaurants.
Every year in April and September Zagat makes his rounds of New York restaurants, like a Bishop inspecting his diocese. There are over 30 different Zagat guides, covering dozens of different North American cities.
