Restoran Pak Datuk serves very nice and authentic nasi padang (Indonesian rice with dishes). When seated the waiters will present you with many plates of Indonesian dishes. Just tuck in and you'll be charged according to what you have taken.
Favorite Dish: Ayam pop, curry chicken and fried fish (don't know what's the name of the fish, but it's very small but slightly bigger than ikan bilis).
For drinks, order 'terung belanda'.
