The Hakone restaurant is on the first floor of the Prince Hotel, with Lake Ashi outside the window, and beautiful scenery. We arrived at 5:30 in the evening, and there were not many customers because it was not the peak season. The tableware was exquisite, and the next dish would be served immediately after you finished one dish. The waiters were very enthusiastic. I talked to them about the history of this restaurant and learned that it hosted the dinner of the Seven Nations Conference in 1986. The head office of this restaurant, Tokyo Yotsuya, has been established for exactly 190 years.
