In a small white clapboard building no larger than a ranch house, Woo Jung Restaurant is serving Korean and Korean-style Chinese food on mismatched plates that reinforce the homey feeling. The Ayer spot sends five small complimentary bowls of banchan to the table first: daikon, cucumber, kimchi, “American’’ kimchi, and bean sprouts with sesame oil. Most are spicy; all are crunchy and delicious. An appetizer of kimchi pancake ($12) is perfectly cooked, if a bit salty. Kalbi, Korean short ribs ($18.50), bathed in a slightly sweet soy-based barbecue sauce, come with scissors for easy cutting. This is a family affair with a dad, his two sons, and one son’s wife in the dining room. The restaurant is best known for noodle dishes - particularly ja jang myun (with pork) and jam bong (in a seafood soup with pork and vegetables). You’d think someone’s mother is in the kitchen - and there is. The brothers’ mom is often at the stove. Woo Jung Restaurant, 174 W. Main St., Ayer, 978-772-5742.
