Well I've visited there a few times. I know some locals. I think the food scene is quite good there. I'm not sure about the living situation yet, but it is a typical third world country city that has super nice neighborhoods adjacent to the most depressingly poor of slums. It's definitely a notch or two down the ladder from Thailand, but the people are just as friendly. My biggest pet peeve about Phnom Penh is the dirtiness. Giant piles of trash on street corners, etc.
