The purpose of this study is to suggest valuable directions and to produce basic data for their policy decisions by restaurant managers for 'Globalization of Korean Food' by comparing Korean restaurants with foreign restaurants. This study was based on the "Hedonic Price Model" with data from 'ZAGAT New York City 2011'. We used diners' survey data on food, decoration, and service from 621 different types of restaurants including American, Southeast Asian, Australian, Philippine, Korean, Japanese, Chinese, Malaysian, Noodle, Seafood, Vietnamese and Thai food. Results of regression analysis revealed that the factors affecting price decision are the food, the decoration/atmosphere, and the service. In other words, customers are happy to pay when they are satisfied with the food, the decoration/atmosphere, and the service. In order to have competitiveness in USA for Koran restaurants, it is important to concentrate on these factors and with highest priority on "food".
