The Zagat Survey is a restaurant rating and review system that provides insights into dining experiences. Founded in 1979 by Tim and Nina Zagat, it collects feedback from diners to create comprehensive guides for various cities. The survey covers aspects like food quality, service, and ambiance, allowing users to make informed dining choices. Zagat ratings are based on a scale of 1 to 30, with higher scores indicating better experiences. The guides are published in print and online, and they have expanded to include reviews for hotels and attractions, making them a valuable resource for travelers and food enthusiasts alike.
