On the weekend, Kim Son's carts carry an average of 70 dim sum items. Don't miss the velvety eggplant stuffed with shrimp paste, mushroom-capped meatballs, Chinese broccoli, golden-fried turnip cakes, slurpy rice noodle rolls, cylinders of shrimp paste wrapped in seaweed and deep-fried in tempura batter, pork dumplings with quail eggs inside, or the sweet taro roll covered with almonds. But wait, you say, dim sum is Chinese, so how could the best dim sum in Houston be served at a Vietnamese restaurant? "I was born here in the States, but like the owners of Kim Son, my family is Chinese-Vietnamese," explains Andy Troung, the manager of the Stafford location. "Chinese people ate dim sum all the time in Vietnam. So eating dim sum in a Vietnamese restaurant in Houston makes perfect sense to Chinese-Vietnamese-Americans like me."
