Through the study, the recognition level of Korean food is high, most Chinese tourists could accept the taste of Korean food, but the performance is totally different due to the limitations of the group visitors; the time and language of independent tourists.

Korean tourism administration need to establish a guide standard for group visitors to protect the experiences of Korean food; and need to develop some sets for independent tourists; develop some food tourism product routes; and create some famous food tourism festivals or events. Try to find some tourism food products which fit the taste of Chinese tourists, and to carry out the promotion tactics according to the characteristics of the product, try to combine the ideas of delicious, health and cultural heritage, so that visitors can enjoy variety of flavors of Korean food.
