People basically eat just to have something in their stomach unlike Thai, Malaysia etc where eating is a big deal.
Not much effort goes into cooking. And many places use the cheapest ingredients partly to keep prices low. If it's chicken it will be a bit of neck.
There is a very good rice called 7 tonner. It costs more so not in many restaurants.
Also to save money the rice is cooked on a fire. It often means the bottom of the pot has burnt rice and the top has uncooked rice.
There is an ok dish with mung beans cooked in coconut milk. That's about as elaborate as it gets.
The PI is the only place I have eaten pizza.
