In Phnom Penh city, there is a co-city calling ‘Camko City’ near Tuol Kok arena.
When you enter the road to the city, you will see on your left hand a eatery place, no air conditioner, only fans.
Fried Beef with Khmer Source
The food there is tasty and appropriate price.
I went with my colleagues, eat grilled beef with prahok and fried beef with source (សាច់គោឆាគ្រឿង). We did not drink beer, only Coke and fruit juice (can).
