Eating the Globe: Cambodia

I usually don't like restaurants that specialize in two cuisines. That's why I wouldn't normally go to a place called Thaibodia. It's half Thai, half Cambodian. But today, I was in an unfamiliar place, was hungry, and in a hurry. 

This is the "Spicy Garlic Butter Sauce with Rock Cod" that I had for lunch. It's potatoes, corn kernels, and cod in a red, smoky sauce. I can't tell how authentic it is. I've never associated Cambodia with potatoes and corn. The sauce almost had a Mexican flavor.
