The best 2 Singapore chicken rice in Tokyo 

Called Hainan jee fan(海南鶏飯), Singapore chicken rice has become popular in recent years in Japan. If you wish to have the most authentic one in Tokyo, I recommend the following places: Hainan Jee Fan Shokudo(海南鶏飯食堂) in Roppongi or Song Kee Jee Fan(松記鶏飯) in Awaji-cho, nearby Kanda.
