I have been sharing with people about the most hot and spicy nasi katok that I have tasted in Brunei, it is located at Jalan Madang, Bandar Seri Begawan, Brunei Darussalam,close to simpang 140 and Jalan 1. Or check http://m.google.com/u/m/z0zzL5 I found that a drink of coconut or chocolate milk shake or ice cream helps reduce the stomach upset later on. Have fun š
