Tucked into a small store front restaurant, Sun Tung turns out fresh and tasty dishes without MSG and at very reasonable prices. Located at 153 S. B Street in San Mateo (650) 342-5330, this family restaurant has been serving customers for approximately 20 yrs. and is still a favorite of the locals. They serve familiar choices like excellent hot & sour soup and kung pao chicken, prawns and squid, but they will also prepare dishes from Northern China, their former homeland, if asked. We asked that they "surprise" us with a dish from their homeland and all 6 of us thoroughly enjoyed a heaping plate of various vegetables, tofu and chicken in a special sauce. It was full of flavor. Since we don't know the name of this dish, we will simply ask to be "surprised" again. You will not be disappointed with whatever you order!
