I haven't had a lot of Khmer food, even during my short visit to Cambodia in 2007 I can't quite remember what I ate (other than a deepfried tarantula).
We'd had a good amount of Vietnamese food around Houston but it was good to see some lesser popular Asian cuisines to break up the food trip.
Phnom Penh Noodle House Special (slice pork, ground pork, liver, pork meat balls, chicken, crispy duck, shrimp) USD11 and Shrimp Noodle Soup USD8 garnished with fried garlic, cilantro, scallions. A clear warming delicious soup, with a simpler flavour than pho but no less delicious with it's pork base, rather than beef.
