Since Biro Tatanegara has been a hot issue of late, I will share my own experiences. I have gone to two BTN courses under PNB and Mara. To be honest, I have mixed feelings about it.
The food at BTN is amazing. They may be simple Malaysian dishes like 'ikan kembung goreng' or 'sayur campur' but somehow even the steamed rice has some magic in it.
