Ryu no Ko (龍の子) is a restaurant located in the Harajuku neighborhood of Shibuya-ku, Tokyo, Japan.
The restaurant's name means "Dragon's Child", and may be a reference to the exceptional (by Tokyo standards) spiciness of its Szechwan-style fare. The restaurant was opened in 1977 by Tetsuji Yasukawa (安川哲二), a celebrity who has appeared on Japanese television and in a compilation cookbook.
The restaurant is small and popular, so reservations are recommended.
